Figure 1 is a flow chart of an embodiment of an information transmission method provided in the embodiment of the present application, and the method may include the following steps:

101: The sending end encodes the information to be transmitted to obtain an encoded image.

102: Decompose a frame of image to be transmitted transmitted at a preset frame rate to obtain a low-frequency image composed of low-frequency information and a high-frequency image composed of high-frequency information.

103: After loading the image information of the coded image into the low-frequency image, fuse it with the high-frequency image to obtain an image to be processed corresponding to the image to be transmitted.

The one frame of images to be transmitted may be one frame of video images, and the preset frame rate is the frame rate of the video images.

In the embodiment of the present application, the image to be transmitted is decomposed to obtain a low-frequency image and a high-frequency image. Since the human eye perceives the high-frequency part and the low-frequency part of the image differently, the high-frequency part contains image detail information. For a high-resolution image, the high-frequency information is missing, and the human eye will feel that the image is distorted. blurred, but the human eye does not have a keen perception of the low-frequency part of the image, and the low-frequency part is not easily perceived by the human eye. To this end, the image to be transmitted is decomposed into a low-frequency image formed by low-frequency information that is not easily perceived by the human eye, and the image information of the encoded image is superimposed on the low-frequency image, so that the encoded image cannot be perceived by the human eye and does not affect The display effect of the image.

The low-frequency image of the image information of the coded image is loaded, and then fused with the high-frequency image, so that the image to be processed and the image to be transmitted can be obtained.

The image to be processed and the image to be transmitted have the same information perceived by human eyes, except that the image to be processed includes image information of a coded image that cannot be perceived by human eyes.

The loading of the coded image to the low-frequency image may specifically be loaded into an image of a certain area of the low-frequency image that matches the size of the coded image, and the image intensity of the coded image and the image intensity of the image of the certain area may be processed according to a preset reversible algorithm.

The preset reversible algorithm may be addition, subtraction, division, multiplication, or convolution operations among image intensities.

104: Use the image to be processed and the image to be transmitted as two adjacent frames of images, and transmit the image to be processed and the image to be transmitted at twice the preset frame rate.

The image to be processed obtained from the image to be transmitted can form two adjacent frames of images. In order not to affect the viewing effect of the video, the image to be transmitted and the processed image are transmitted according to twice the preset frame rate, that is, the original video can be realized. The display effect of the image.

After the receiving end acquires the image to be processed and the image to be transmitted, it can decompose the image to be processed and the image to be transmitted respectively; according to the low-frequency image of the image to be transmitted and the image to be processed The low-frequency image of the image is used to restore the coded image and decode the information to be transmitted.

The low-frequency image in the image to be processed is loaded with a coded image, so the coded image can be restored according to the low-frequency image of the image to be transmitted and the low-frequency image of the image to be processed.

When the encoded image is loaded into the image according to the preset reversible algorithm, the receiving end restores the encoded image according to the low-frequency image of the image to be transmitted and the low-frequency image of the image to be processed. A reversible algorithm is used to restore the coded image.

For example, when the preset reversible algorithm is an addition operation or a subtraction operation, the receiving end may specifically subtract the image intensity of the low-frequency image of the image to be transmitted from the image intensity of the low-frequency image of the image to be processed to obtain a coded image .

When the preset reversible algorithm is a multiplication operation or a division operation, the receiving end may specifically divide the image intensity of the low-frequency image of the image to be transmitted by the image intensity of the low-frequency image of the image to be processed to obtain a coded image.

In this embodiment, the sending end encodes the information to be transmitted into a coded image, loads it into the low-frequency image part of the image to be transmitted, and after forming the image to be processed, forms two adjacent frames of image transmission with the image to be transmitted. When the receiving end acquires After obtaining the image to be processed and the image to be transmitted, the image to be processed and the image to be transmitted can be decomposed respectively; according to the low frequency image of the image to be transmitted and the low frequency image of the image to be processed , restore the coded image, and decode the information to be transmitted, thereby realizing the hidden transmission of information, increasing the information transmission channel and increasing the amount of information transmission without affecting the user's perception. The receiving end that needs to acquire the transmission information can decode the information to be transmitted from it. For the receiving end that does not have the need to acquire the information to be transmitted, there is no need to decode the information to be transmitted. The receiving end can independently choose whether to obtain the demand to be transmitted, avoiding information bombing The interference caused by the method to the receiver can realize targeted information transmission, optimize the information transmission method, and improve the effectiveness of information transmission.

Especially in the transmission of information such as advertisements or promotional materials in practical applications, the receiver does not have to suffer from meaningless advertisement bombardment, and the receiver who needs it can realize extended reading from the video image and read out the hidden information. Advertising or promotional materials and other information to meet their own needs.

In practical applications, the embodiment of the present application can be applied in places with display screens such as supermarkets, movie theaters, roadsides, bus stops, etc. The advertisements or promotional materials on these display screens are explicit information, and some corresponding text The information is the information to be transmitted. As the implicit information, according to the technical solution of the embodiment of the application, it is superimposed on the video image to promote or supplement the content included in the explicit information. For example, some bus stops are equipped with advertising screens, which do not affect It puts advertisements, and can superimpose implicit information to write relevant information about this product.

For users who have acquisition needs, the superimposed implicit information can be decoded from these explicit information through the receiving end, so that more information can be obtained and targeted information transmission is realized.

In the embodiment of the present application, as a possible implementation manner, the sending end may include a display screen, and the sending end may display the image to be processed and the image to be transmitted after transmitting the image to be processed and the image to be transmitted at twice the preset frame rate. Therefore, acquiring the image to be processed and the image to be transmitted by the receiving end may be through its camera unit capturing the image to be processed and the image to be transmitted.

The sending end may be, for example, a TV, a tablet computer, a computer, and other equipment, and the receiving end may be a mobile phone, a tablet computer, or other equipment with a camera.

Wherein, the sending end displays the image to be transmitted and the image to be processed can be realized based on visible light multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) communication technology, and the display screen of the sending end is a liquid crystal display screen (Liquid Crystal Display, LCD).

As another possible implementation, the image to be processed and the image to be transmitted are two adjacent frames of images, and the sending end transmits the image to be processed and the image to be transmitted at twice the preset frame rate The image to be processed and the image to be transmitted may be sent to the receiving end at twice the preset frame rate, so that the receiving end that needs information acquisition can decode the decoded information in the encoded image.

As yet another possible implementation, the sending end can transmit the image to be processed and the image to be transmitted to a display device with a display screen at twice the preset frame rate, and the display device can double the preset frame rate. The image to be processed and the image to be transmitted are displayed at a preset frame rate. The acquisition of the image to be processed and the image to be transmitted by the receiving end may be the image to be processed and the image to be transmitted displayed on the display device captured by its camera unit.

The display screen of the display device may be an LCD, and the display of the image to be processed and the image to be transmitted by the display device may be implemented based on visible light MIMO communication technology.

Among them, encoding the information to be transmitted to obtain an encoded image may have multiple implementation manners.

In a possible implementation manner, a two-dimensional code encoding manner may be used to obtain an encoded image.

Specifically, in this embodiment of the application, the information to be transmitted may be coded according to the two-dimensional image coding format to form a coded image, so that the coded image includes the image positioning mark and the information synchronization mark stipulated in the two-dimensional image coding format And the two-dimensional code word of the information to be transmitted.

Wherein, the image positioning mark is used to determine the position of the coded image, the information synchronization mark is used to mark the transmission sequence of different information to be transmitted, and the two-dimensional codeword is a codeword after encoding the information to be transmitted.

Since the coded image is loaded into an image in a certain area of the image to be transmitted, the image location identifier is used by the receiving end to locate the position of the coded image.

There may be multiple pieces of information to be transmitted, and each piece of information to be transmitted is loaded into an image to be transmitted. Therefore, the information synchronization identifier can be used to identify the transmission sequence of different information to be transmitted.

A two-dimensional code word usually consists of two different color pixels representing binary 0 and 1 respectively, and the code word is obtained after arranging according to a certain rule.

In order not to affect the display effect of the image to be transmitted and increase the privacy of the information to be transmitted, the two-dimensional code can use black and gray pixels to represent binary 0 and 1.

As shown in Figures 1a-1b, they are two encoded images obtained after encoding two pieces of information to be transmitted.

In the figure, the image positioning mark 100 is used to determine the position of the encoded image, and the image positioning mark is the same in each encoded image. The information synchronization mark 200 is used to identify the transmission sequence of different information to be transmitted. As shown in Figure 1a, the information synchronization mark is marked with black pixels, and in Figure 1b, the information synchronization mark is marked with gray pixels, and the two coded images in Figure 1a and Figure 1b are transmitted in order , so the receiving end can determine that the encoded image with the black pixel identifier and the encoded image with the gray pixel identifier are two adjacent frames of images according to the black pixel identifier and the gray pixel identifier.

Wherein, the information to be transmitted sent by the sender can be a part of the total data to be transmitted, and the sender needs to transmit the total data to be transmitted, and can divide the total data to be transmitted to obtain multiple divided data, and each divided data is It can be used as a piece of information to be transmitted, and the image to be transmitted and the image to be processed corresponding to each divided data are obtained according to the operation of steps 102 to 104, and the image to be transmitted and the image to be processed corresponding to each divided data are used as two adjacent The frame image is transmitted according to twice the preset frame rate, so that the image to be transmitted and the image to be processed are separated by frames, and the image to be transmitted corresponding to each divided data can form a continuous multi-frame image. Therefore, as another embodiment, as As shown in Fig. 2, a flow chart of another embodiment of an information transmission method provided by the embodiment of the present application, the method may include the following steps:

201: The sending end divides the total data to be transmitted to obtain a plurality of divided data, sequentially encodes each divided data as information to be transmitted, and obtains an encoded image corresponding to each divided data.

When the amount of total data to be transmitted is too large to be loaded into one frame of image to be transmitted, the total data to be transmitted can be divided into multiple divided data, and each divided data is a piece of information to be transmitted.

The plurality of divided data has a transmission order, and according to the transmission order, the plurality of divided data can be combined into the total data to be transmitted, and the obtained encoded image is transmitted according to the transmission order.

202: Determine a frame of images to be transmitted corresponding to each divided data and transmitted according to a preset frame rate.

Among them, multiple frames of images continuously transmitted in the video image may be selected according to the transmission sequence of the coded images, and one frame of images may be sequentially selected according to the sequence of the multiple frames of images as the image to be transmitted and assigned to each divided data.

203: Decompose the image to be transmitted into a low-frequency image composed of low-frequency information and a high-frequency image composed of high-frequency information.

204: After loading the image information of the coded image into the low-frequency image, fuse it with the high-frequency image to obtain an image to be processed corresponding to the image to be transmitted.

The operations of steps 203 to 204 are performed for a frame of image to be transmitted corresponding to each divided data, so that the image to be transmitted and the image to be processed corresponding to each divided data can be obtained.

205: Combine the image to be processed and the image to be transmitted corresponding to each divided data into two adjacent frames according to the sequence of image transmission.

206: Continuously transmit the image to be processed and the image to be transmitted at twice the preset frame rate.

The image to be processed and the image to be transmitted corresponding to each divided data form two adjacent frames, and the image to be processed and the image to be transmitted corresponding to each divided data are transmitted at twice the preset frame rate, that is, the multiple divided data are respectively The corresponding images to be processed are transmitted at intervals of frames, and the images to be transmitted are transmitted at intervals of frames, so that the perception of the user may not be affected.

Other frame images of the video image can be transmitted according to the preset frame rate, or the same image frame can be copied separately to form two adjacent frames of images, so the video can be transmitted at twice the preset frame rate image.

Each segmented data can be coded according to a two-dimensional image coding format to form a corresponding coded image. The coded image includes an image positioning mark specified in the two-dimensional image coding format, an information synchronization mark, and a two-dimensional code word of the information to be transmitted, and the image positioning mark is used to determine the position of the coded image, so The information synchronization identifier is used to identify the transmission sequence of the information to be transmitted.

Therefore, according to the information synchronization identifier, the receiving end can combine the plurality of divided data into the total data to be transmitted according to the identified transmission sequence.

In this embodiment, the sender first divides the total data to be transmitted into a plurality of divided data, and each divided data is used as information to be transmitted, and is encoded into a coded image. Determine a frame of image to be transmitted for each divided data from the transmitted video image, load the encoded image to the low-frequency image part of the image to be transmitted, form the image to be processed, and form two adjacent frames of image with the image to be transmitted , so that during video image transmission, the image to be transmitted and the corresponding image to be processed are transmitted according to twice the preset frame rate, so that after the receiving end acquires the image to be processed and the image to be transmitted corresponding to two adjacent frames, That is, the image to be processed and the image to be transmitted can be decomposed respectively; according to the low-frequency image of the image to be transmitted and the low-frequency image of the image to be processed, the coded image is restored, and the information to be transmitted is decoded, thereby It can realize the implicit transmission of information without affecting the user's perception, increase the information transmission channel, and increase the amount of information transmission. For the receiving end that needs to obtain the information to be transmitted, it can decode the information to be transmitted from it. The receiving end of the demand does not need to decode the information to be transmitted. The receiving end can independently choose whether to obtain the demand to be transmitted, avoiding the interference caused by the information bombing method to the receiving party, enabling targeted information transmission, and optimizing the information transmission method.

Fig. 3 is a flow chart of another embodiment of an information transmission method provided by the embodiment of the present application, and the method may include the following steps:

301: The receiving end obtains an image to be transmitted and a corresponding image to be processed in two adjacent frames transmitted by the sending end at twice the preset frame rate.

Wherein, the image to be processed is generated as follows:

The sending end encodes the information to be transmitted to obtain a coded image; decomposes the image to be transmitted to obtain a low-frequency image composed of low-frequency information and a high-frequency image composed of high-frequency information; loads the image information of the coded image After reaching the low-frequency image, it is fused with the high-frequency image to obtain an image to be processed corresponding to the image to be transmitted.

Since the human eye perceives the high-frequency part and the low-frequency part of the image differently, the high-frequency part contains image detail information. For a high-resolution image, the high-frequency information is missing, and the human eye will feel that the image is distorted. blurred, but the human eye does not have a keen perception of the low-frequency part of the image, and the low-frequency part is not easily perceived by the human eye. For this reason, in the embodiment of the present application, the image to be transmitted is decomposed into a low-frequency image formed by low-frequency information that is not easily perceived by the human eye, and the image information of the encoded image is superimposed on the low-frequency image, so that the encoded image cannot be detected It is perceived by the human eye and does not affect the display effect of the image.

The image to be transmitted may be a frame of image in the video image selected for transmission.

The image to be transmitted and the corresponding image to be processed constitute two consecutive frames of images, which are transmitted in the video image.

The preset frame rate is the original frame rate of the video image. After adding the image to be processed, the image to be transmitted and the image to be processed are transmitted at twice the preset frame rate to ensure the display effect of the video image.

302: Separately decompose the image to be processed and the image to be transmitted to obtain a low-frequency image of the image to be processed and a low-frequency image of the image to be transmitted.

303: Restore a coded image according to the low-frequency image of the image to be transmitted and the low-frequency image of the image to be processed.

When the sending end processes the image intensity of the coded image and the image intensity of a certain area of the low-frequency image decomposed from the image to be transmitted according to the preset reversible algorithm, and then fuses with the high-frequency image to obtain the image to be processed corresponding to the image to be transmitted In this case, step 303 may be specifically to restore the coded image from the low-frequency image of the image to be transmitted and the low-frequency image of the image to be processed according to the preset reversible algorithm.

For example, when the preset reversible algorithm is an addition operation or a subtraction operation, the receiving end may specifically subtract the image intensity of the low-frequency image of the image to be transmitted from the image intensity of the low-frequency image of the image to be processed to obtain a coded image .

When the preset reversible algorithm is a multiplication operation or a division operation, the receiving end may specifically divide the image intensity of the low-frequency image of the image to be transmitted by the image intensity of the low-frequency image of the image to be processed to obtain a coded image.
