Description

How to replace objects in dynamic images

technical field

The present invention relates to a method for replacing objects in an image, especially a method for replacing objects in a dynamic image, wherein the dynamic image is a dynamic image file or a real-time dynamic image to provide users with more choices To replace real-time dynamic images and objects in the dynamic images to achieve better entertainment effects.

Background technique

For today's information users, especially personal computer users, the mode of contacting computer information has entered the era of so-called Multi-Media from the relatively monotonous text mode, and multimedia means that the information includes text , video, audio and other content, and in order to present the data in the form of multimedia in front of the audience, a variety of multimedia devices that can capture video or audio have been developed. Because the multimedia data contains more content, the memory capacity required to process the multimedia data needs to be higher than the monotonous text mode, so that the multimedia data can be presented in a smoother mode.

For image input devices, scanners, digital video cameras, and digital cameras are relatively common devices at present. Digital cameras use digitized information to store captured still images. The digital video camera uses digital information to store the captured still images. The data of the still image and the dynamic image all use a disk that can record the image or a memory card of the Personal Computer Memory Card International Association (PCMCIA) to store the image data. In order to save the memory space used by the storage media, images captured by digital cameras are usually stored in compressed files, and the common one is the still image compression standard (Joint Photographic Experts Group; JPEG) file format. Digital video cameras usually use the AVI multimedia playback format to store.

The AVI multimedia playback format is a file format defined by Microsoft Corporation (Microsoft) in the video and audio files (Video for Windows) developed for the window system. Among the files belonging to the AVI multimedia playback format, data streams (data streams) of many different types of media can be stored. Each data stream can be an independent medium, for example: image data stream, audio data stream, text data stream, etc. The application programs that support the AVI multimedia playback format must be able to perform synchronous playback of these data streams. Therefore, the AVI multimedia playback format is one of the most important file formats in the multimedia field.

AVI files can be played without special hardware equipment, so they are widely circulated on personal computers (personal computers; PCs). Because this file format divides the animation into static images, and only the difference between the subsequent images and the previous images is stored, so some pixel comparisons must be done before playback, and only about 20 images can be played per second. frame images, and these images are usually only half the size of the screen.

The files in the general digital video camera can be stored as a file in AVI multimedia format after being transferred to the computer. And when a Charge-Coupled Device (CCD) is connected to a computer, a real-time dynamic image can be obtained on the screen. A so-called charge-coupled device is a light-sensitive circuit arrangement. A digital camera or a digital video camera uses the information remaining on the charge-coupled device to convert the sensitivity of each dot element to light into digital image data for storage.

In the traditional method, when playing a dynamic image file in a multimedia format, if you want to hide some objects in the dynamic image file, such as a human face, you usually use a foggy method to combine the foggy format with the Some elements in the dynamic image file overlap each other, so that the viewer cannot clearly see the real appearance of some elements. However, this fogging method cannot be applied to real-time dynamic image files, and this fogging method cannot fully protect the full picture of the object to be hidden due to the different setting values of the fogging degree. Moreover, this foggy method can be easily cracked by software or hardware and loses the meaning of hiding some objects. Therefore, the traditional method of using fog to conceal some objects in the dynamic image file may cause inconvenience to the user and fail to achieve the effect of entertaining the public.

Contents of the invention

Next, a playback program is used to execute the file of the moving image, such as a file in the AVI multimedia format, or a charge-coupled device is used to display a real-time moving image on the screen. When the dynamic image is playing, the program of the present invention starts to search for the first object in the dynamic image from the object characteristics in the first database. In the object feature comparison program, the program of the present invention uses a similarity to search for the first object included in the dynamic image and performs an object feature comparison process. When the similarity of the searched object is determined to be greater than a set value through the feature comparison program, it is determined that the searched object is the first object. Next, the second object stored in the second database is used to replace the first object in the dynamic image being played. In the process of playing the dynamic image, the user can use the user interface to capture a static image in which the first object is replaced by the second object. After the dynamic image is played, the user can choose whether to replace the dynamic image of the first object with the dynamic image of the second object on the user interface. When the first object to be replaced is a plurality of first objects and different first objects need to be replaced with different second objects, the moving trajectories of the different first objects in the dynamic image can be used to classify, and replace the first object of the same class with the same second object.

Referring to Fig. 1, this is the first flow chart of the present invention. Firstly, the user must install and drive the program 100 provided by the method of the present invention. Next, the user can set the real-time dynamic image file to be replaced or the first object in the dynamic image file on the user interface, and select the second object 110 to replace the first object on the user interface.

Next, a playback program is used to execute the dynamic image file, such as a file in AVI multimedia format, or a charge-coupled device is used to display a real-time dynamic image 120 on the screen. When the moving image or the real-time moving image is playing, the program 130 of the present invention searches for the first object in the moving image based on the object characteristics in the first database and compares the object characteristics. In the object feature comparison program, the program of the present invention searches for the first object included in the dynamic image according to a similarity degree, and judges whether the similarity degree is greater than a set value 140 . When the similarity of the searched object is determined to be greater than a set value through the feature comparison program, it is determined that the searched object is the first object 150 . When it is determined that the similarity of the searched object is not greater than a set value through the feature comparison process, it is determined that the searched component is not the first component 160 to be replaced. Next, the second object stored in the second database is used to replace the first object 170 in the dynamic image being played.

The following description is one of the embodiments of using the method of the present invention to replace some components in the dynamic image, wherein the dynamic image is a dynamic image file or real-time dynamic image, but does not limit the protection scope of the present invention.

Generally, pictures of characters are included in the dynamic image. If the characters on the film want to hide their true faces without being recognized by the viewers, traditional methods are usually used to treat the characters on the film. Faces are fogged so that users cannot recognize the real faces of the people on the video. But this kind of mist treatment is easier to be deciphered by people, and it is also easier to destroy the overall beauty of the image. Therefore, the method of the present invention must be used to protect the privacy of the characters in the film, and increase the entertainment and aesthetic effects.

Firstly, the program provided by the method of the present invention must be installed and driven on the computer. Next, the user can use the user interface to select one or more patterns from the various patterns stored in the second database to replace the faces of the characters in the dynamic image. A variety of graphics stored in the second database, usually the faces of animals, to increase the entertainment effect when broadcasting dynamic images. If only a single character appears in the dynamic image file, the user only needs to select an image on the user interface to replace the face of the single character in the dynamic image in subsequent steps. If multiple different characters appear in the dynamic image, the user can sequentially select different images on the user interface to replace faces of different characters in the dynamic image in subsequent steps. The user can also select only one image on the user interface, but when the moving image is played, the faces of different characters will be replaced by the same image.

Next, the user can start to play the dynamic image, wherein the dynamic image is a dynamic image file or a real-time dynamic image. While playing the video, the program of the present invention uses the features stored in the first database to search for human faces and perform a similarity judgment. Because this embodiment replaces the faces of the characters in the dynamic image, the feature values stored in the first database are all feature values for judging human faces, such as skin color, the position of facial features, and the color of eyes, etc. . In the process of searching faces, a similarity judgment must be performed at the same time. When the similarity obtained after comparing the object in the dynamic image with the feature value stored in the first database is greater than a set value, it is determined that the object is a human face. If the similarity obtained after comparing the object in the dynamic image with the feature value stored in the first database is not greater than a set value, it is determined that the object is not a human face. If there are many different faces in the dynamic image, they are distinguished as different faces by the different trajectories of the different faces moving in the dynamic image, and they are numbered in sequence so that each different face corresponds to the user. or a different image selected on the user interface.

After recognizing the face of the person in the dynamic image, the image selected by the user on the user interface is replaced with the face of the person. Viewers can only see an image that replaces the face of the person on the screen, and cannot know the real appearance of the person in the dynamic image. According to the different needs of the users, the user can use the user interface of the program of the present invention to capture one of the images as a static image when playing the dynamic images. After the dynamic image file is played, the user can also use the user interface to choose whether to replace the original dynamic image file with the dynamic image file with the image replacing the face of the person, or to replace the dynamic image file with the image instead of the face of the person separately. Save as a new motion picture file. When using the image from the second database to replace the face of the person in the video, the image replacing the face can be enlarged or reduced according to the size of the face in the video, so it is not easy for the viewer to know the dynamics The real face of the person in the image. When a file that replaces a person's face with an image is saved as a new file, the face of the person in the moving image file has been replaced by an image, so other people cannot know the identity of the person in the moving image file in other ways Therefore, the privacy of the characters in the film can be protected and the entertainment effect of the film can be increased.

Referring to FIG. 2 , this is the second flowchart of the present invention. The second flow chart is a flow chart of using the method of the present invention to replace the faces of people in the dynamic image with images. Firstly, the program provided by the method of the present invention must be installed on the computer and the program 210 must be driven. Next, the user can use the user interface to select a pattern or patterns 220 from various patterns stored in the second database to replace the faces of the characters in the dynamic image. Next, the user can start to play the dynamic image, wherein the dynamic image is a dynamic image file or a real-time dynamic image 230 . While playing the video, the program of the present invention searches for human faces from the features stored in the first database and performs a similarity judgment 240 . When the similarity between the object in the dynamic image and the feature value stored in the first database is greater than a set value, it is determined that the object is a human face 250 . If the similarity between the object in the dynamic image and the feature value stored in the first database is not greater than a set value, it is determined that the object is not a human face 260 . If there are many different faces in the dynamic image, they are distinguished as different faces by the different trajectories of the different faces moving in the dynamic image, and they are numbered in sequence so that each different face corresponds to the user. or a different image selected on the user interface. After the face of the person in the dynamic image is recognized, the image selected by the user on the user interface is then replaced with the face of the person 270 .

To sum up the above, the present invention provides a method to replace real-time dynamic image files and some objects in the dynamic image files by using the identification of features in the database and the replacement of objects, so as to truly conceal the real-time dynamic image files or all objects in the dynamic image files. Part of the object to be hidden. The replacement method of the present invention is to use a program to replace real-time dynamic images and objects in the dynamic images, wherein the above-mentioned program includes a first database, a second database and a user interface (user interface). The content stored in the first database is a plurality of characteristics of the first object to be replaced in the dynamic image. The content stored in the second database is the second object to replace the first object. When the dynamic image is played, the program of the present invention searches for the first object in the dynamic image from the object characteristics in the first database and performs a comparison of object characteristics. In the process of object feature comparison, the program of the present invention searches for the first object contained in the dynamic image by a similarity. When the similarity of the searched object is determined to be greater than a set value through the feature comparison program, it is determined that the searched object is the first object. Next, the second object stored in the second database is used to replace the first object in the dynamic image being played. In the process of playing the dynamic image, the user can use the user interface to capture a static image in which the first object is replaced by the second object. After the dynamic image is played, the user can choose whether to replace the dynamic image of the first object with the dynamic image of the second object on the user interface. When the first object to be replaced is a plurality of first objects and different first objects need to be replaced by different second objects, different first objects can be used to move within the dynamic image or real-time dynamic image trajectories, and replace the first object of the same class with the same second object.
