Description

APP icon update system

Technical field

The present invention relates to the field of icon management, and specifically relates to an APP icon update system.

Background technique

At present, the main products of companies, website platforms, etc. are APPs, and APPs all have APP icons, so the APP icons have become their own logos for companies and website platforms. When participating in a group meeting held by a certain company, the company's PPT often displays its main customers, and these customers are often APPs. When displayed, only icons are displayed, and no text is given to describe the specific customer names. Some apps are not particularly well-known. You can’t tell who they are by just looking at the icon. You need to search on site to find out.

Currently, the commonly used icon retrieval method is to use Baidu image recognition for retrieval, but this retrieval has the following shortcomings: (1) The speed is slow. The main reason for the slow speed is that there are so many pictures on the Internet, so the number of pictures in the picture library that needs to be established through traditional methods is also very large, and the content-based image retrieval operation is relatively large, resulting in low retrieval efficiency. (2) The accuracy is low. For the description text of each image, due to the Internet crawling engine, only the text near the image can be obtained, so the accuracy of describing the image is low. (3) Resource consumption is large. In addition, when the image resolution is high, establishing feature vectors of images with comparable similarity for a large number of images in the image database itself also requires a huge amount of software and hardware resources.

Therefore, there is an urgent need to provide a retrieval solution that can quickly and accurately retrieve matching APP icons.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

Figure 1 is a schematic structural diagram of an APP icon updating system provided by an embodiment of the present invention. As shown in Figure 1, the APP icon updating system provided by the embodiment of the present invention includes a server 101 and a mobile terminal 102 for information interaction. Among them, the server 101 is used to download APP icons and APP information of M APPs from multiple third-party servers 105, and store the downloaded APP icons and APP information in the server database 103, and according to the preset The update cycle updates the M APPs stored in the server database 103, and stores the K APPs with the highest download volume among the M APPs in the fast cache 104. The union of the top K1 APPs sorted by the total download volume in the third-party servers 105 and the top K2 APPs sorted by the updated download volume of the plurality of third-party servers 105 within the set time, for example, K1=500 , that is, the top 500 APPs in multiple third-party servers from the date of APP release to the current total download volume, for example, K2 = 200, which is the number of downloads in multiple third-party servers within the scheduled update cycle, such as within the last three days. Update the top 200 APPs by download volume; the APP information includes APP ID, APP name, developer, version number, introduction, and APP download volume. K APPs are stored in the terminal database of the mobile terminal 102, including K3 APPs sorted by total download volume and K4 APPs sorted by update download volume. The K APPs in the terminal database are updated according to the preset Update is performed in such a way that the K APPs in the terminal database are the same as the K APPs in the server database; where M is greater than or equal to 1 million; K is much less than M.

Specifically, the server 101 can crawl APP icons and APP information from multiple, for example, N third-party servers 105 through crawlers. The APP information includes APP ID, APP name, developer, version number, profile, and APP download volume. wait. Basically, by downloading commonly used app stores such as Huawei, Xiaomi, OPPO, Wandoujia, Apple App Store, and Google, you can obtain the APP information of M APPs, APP icons, and the image feature values of the icons. In one example, the server 101 pre-processes the APP icon and APP information (for example, merges them according to the ID of the APP, etc.) and then stores them in the server database 103. The server 101 will download the APP icon and APP information regularly (for example, every day) and update the server database 103. In this way, it can ensure that the M APPs and K APPs can be updated in a timely manner, making the stored APPs as accurate as possible.

In the embodiment of the present invention, K1 may be greater than or equal to five ten thousandths of M, and K2 may be greater than or equal to two ten thousandths of M.

In this embodiment of the present invention, the mobile terminal 102 can maintain synchronization with the server 101 in the following two ways:

Example 1

In this embodiment, the mobile terminal 102 can maintain synchronization with the server 101 in the following manner:

a. The mobile terminal 102 sends its own APP-ID list to the server 101;

b. The server 101 compares the APP-ID list sent by the mobile terminal 102 with its own current APP-ID list, and obtains the APP-ID list that needs to be added and the APP-ID that needs to be deleted by the mobile terminal 102. list, and send the corresponding APP icon and APP information to the mobile terminal 102 according to the obtained list;

c. The mobile terminal 102 adds and deletes corresponding APP icons and APP information in the terminal database according to the APP-ID list that needs to be added and the APP-ID list that needs to be deleted, thereby maintaining synchronization with the server 101.

In this embodiment, since the mobile terminal 102 and the server 101 are synchronized by transmitting an APP-ID list, complete synchronization of APPs between the two can be ensured.

Example 2

In this embodiment, the mobile terminal 102 can maintain synchronization with the server 101 in the following manner:

1. The mobile terminal 102 sends its own APP icon update information to the server 101. The update information includes the time T1 when the mobile terminal was last updated. T1=Null means that the first installation has not been updated;

2. The server 101 obtains the updated APP icons and APP information among the K APPs in the time period T0 to T1 based on the received time T1 and the current time T0, and sends the updated APP icons and APP information to the server 101. For the mobile terminal 102, the APP information also includes the time T2 of the latest update of the APP; the time T2 is used to indicate the time when the APP last existed in K. For example, T2 of the WeChat APP will be very long ago. For example, T1 = February 10, T0 = March 25, then based on the T2 of K APPs on March 25, obtain the APPs of T2 between February 11 and March 25, and obtain this part of the APPs For the newly added APP.

In another example, the APP information sent by the server 101 also includes: the flag KF1 of K1 and the flag KF2 of K2, where KF1 equal to 1 identifies that the corresponding APP-ID belongs to the APP among K1 APPs, and KF2 equals 1 identifies the corresponding APP. The APP-ID belongs to the APP among K2 APPs.

3. The mobile terminal 102 updates the terminal database according to the received updated APP icon and APP information.

Specifically, the mobile terminal 102 writes the received updated APP icons and APP information into the terminal database, and deletes the corresponding APP diagrams and APP information in K3 APPs and K4 APPs from the terminal database, including:

(1) Determine the number K5 and K6 of APPs with KF1 equal to 1 and KF2 equal to 1 based on the received updated APP icon and APP information;

(2) Replace the last K5 APPs among the K3 APPs with the determined K5 APPs, and replace the last K6 APPs among the K4 APPs with the determined K6 APPs.

For example, 6 APPs in server 101 have been updated, 2 of them have KF1=1 and KF2=0; 1 has KF1=0 and KF2=1; the remaining 3 have KF1=1 and KF2=1. Then the mobile terminal 102 will replace the last 5 of the total downloads K3 with 5 with KF1=1, and replace the last 1 of the update downloads K4 with 1 with KF2=1 according to the received APP information.

Compared with Embodiment 1, Embodiment 2 only sends the update time T1 to the server 101 because the mobile terminal 102 can reduce the traffic of the server 101 .

In the APP icon update system provided by the embodiment of the present invention, the server stores M APPs and selects K APPs whose number is far less than M based on the ranking of the total download volume and updated download volume of the M APPs, and updates these APPs in real time. Update to ensure that the stored APPs are as new and accurate as possible. The terminal database of the mobile terminal stores the same APPs as the K APPs stored on the server side, so that the APPs stored in the mobile terminal are also the latest, which can facilitate the user to select APP icons. Search and ensure the accuracy of the search.

Figure 2 is a schematic structural diagram of an APP icon retrieval system provided by another embodiment of the present invention. As shown in Figure 2, the APP icon retrieval system provided by the embodiment of the present invention includes a server 200 and a mobile terminal 300 for information interaction; the server 200 includes a first storage module 201, a second storage module 202 and an update module. 203. The read and write speed of the second storage module 202 is greater than the read and write speed of the first storage module 201; the first storage module 201 stores APP icons and APP information of M APPs; the second storage The module 202 stores K APPs among M APPs. The K APPs are the union of the first K1 APPs sorted by total download volume and the top K2 APPs sorted by update download volume within a set time. M is greater than or equal to 1 million, and K is much smaller than M. For example, K1 = 500, which is the top 500 APPs from the date of APP release to the current total download volume. For example, K2 = 200, which is within the scheduled update cycle, for example The top 200 APPs with updated download volume in the last three days; the update module 203 is used to update the APPs stored in the first storage module 201 according to a preset update cycle; the APP information includes the ID of the APP and the name of the APP , developer, version number, introduction, APP download volume; the terminal database of the mobile terminal 300 stores K APPs that are the same as the APPs in the second storage module 202 .

In the embodiment of the present invention, the server 200 and the mobile terminal 300 are the same as the previous embodiments, that is, the server 200 downloads and updates APP in the same way as the server 101 in the previous embodiment, and the mobile terminal 300 and the server 200 maintain synchronization. The methods are the same as those in the previous embodiments. To avoid redundant description, their detailed introduction is omitted here.

In the embodiment of the present invention, K1 may be greater than or equal to five ten thousandths of M, and K2 may be greater than or equal to two ten thousandths of M.

In this embodiment of the present invention, when the user needs to retrieve APP icons, the retrieval system performs the following operations:

S100. The mobile terminal 300 obtains the image of the APP icon that the user needs to retrieve, and the image includes the icon area specified by the user for retrieval.

First, the user uses the mobile terminal 300 to take a photo and obtain an image including the APP icon. Then, the user operates the mobile terminal 300 to use a square frame to select the icon area in the image that he wishes to search, that is, to specify the icon area for search. Alternatively, when taking a photo, directly use a square frame to select the APP icon to get the icon area you want to search.

S200. The mobile terminal 300 searches the designated retrieval icon area as a retrieval image in the terminal database to obtain a first retrieval result. If the similarity between the icon represented by the first retrieval result and the retrieval image is greater than If the threshold is first set, the first search result is displayed to the user; otherwise, the search image is sent to the server 200 .

The mobile terminal 300 uses the image in the dotted box as the retrieval input image () to search in the terminal database. Preferably, the mobile terminal 300 extracts the feature value of the image and searches in the terminal database based on the extracted feature value. If the search If a better result is found, it is directly presented to the user; if no better result is retrieved, the image is transmitted to the server. In another example, the feature value of the image is transmitted to the server 200. Using the feature value can significantly Reduce the amount of data transmitted, that is, reduce traffic. In the embodiment of the present invention, "better results" = results in which the similarity between the icon and the input image is greater than the first set threshold, that is, the first search result. "Presented to the user "Preferably, it is presented to the user in the form of "large icon APP icon + text" waterfall flow (sorted according to image similarity), that is, the first search result is displayed in the form of large icon plus text. The text content can include APP information. Image The similarity is calculated based on the image feature values, and existing technology, such as Baidu's technology, can be used.

S300. The server 200 searches the first storage module 201 according to the received search image, obtains a second search result and sends it to the mobile terminal 300. The icon represented by the second search result is the same as the icon represented by the second search result. The similarity of the retrieved image is greater than the second set threshold, and the second search result includes a low-resolution APP icon, APP-ID and similarity.

The server 200 searches among millions of APP icons based on the received retrieval image (preferably the characteristic value of the image), and returns the retrieval result with a similarity greater than the second set threshold, that is, the second retrieval result to the mobile terminal 300 . The second search result may include a low-resolution APP icon, APP-ID and similarity, and optionally also include the APP name and developer, but does not include other information such as a brief introduction. The first set threshold and the second set threshold may be the same, and preferably the first set threshold < the second set threshold to reduce network traffic. The low resolution can be LDPI (Low Density Screen, 120DPI), and its icon size is 36x 36px.

S400. The mobile terminal 300 sorts the received low-resolution APP icons by similarity and displays them in the form of icon blocks.

S500. The mobile terminal 300 receives the icon block selected by the user (for example, clicked), uses the corresponding APP-ID to retrieve the corresponding APP icon and APP information in the first storage module, and displays it; and

S600. The mobile terminal 300 adds the APP-ID and APP information of the icon block clicked by the user to the terminal database.

The APP icon retrieval system according to the embodiment of the present invention has the following technical effects:

(1) Characteristics of APP icons: 1) The resolution is much lower than that of ordinary images, and xhdpi is less than 10,000 pixels, which is far lower than the 20 million pixels of ordinary images; 2) The number of APP icons is in the millions, which is much smaller than that of ordinary images. number of images;

(2) There are only a few hundred APP icons on the mobile terminal, which takes up little space, and image processing and retrieval can be completed directly on the mobile terminal;

(3) Hundreds of commonly used APP icons are on mobile terminals. On the one hand, the probability of hitting the captured image on the mobile terminal is very high, and on the other hand, it also reduces the communication traffic with the server;

(4) It is easy for users to operate. They only need to take pictures, and the real-time performance is good.

Further, in the embodiment of the present invention, the first storage module 201 also stores the first color value of the APP icon and the ratio of the pixels with the first color value to all image pixels. The first color value is the APP icon. The value of the most colors. For example, the main color of Minsheng Bank's APP is white, so the first color value is "white", accounting for 70%.

Further, step S200 also includes:

S201. The mobile terminal 300 obtains the first color value and the second color value of the retrieval image, and the proportion of the pixels of the first color value and the second color value of the retrieval image to all the image pixels of the retrieval image. The first color value and the second color value are respectively the value of the most colors and the second most color of the retrieved image;

S202. If the mobile terminal 300 determines that the ratio of the first color value of the retrieval image is greater than a first threshold, for example, 30%, and the ratio of the first color value of the retrieval image to the second color value exceeds a second threshold, such as 2, then The first color value of the retrieved image and the ratio of the first color value are also transmitted to the server 200. Otherwise, the first color value of the retrieved image is set to Null, and then the first color value and the first color value of the retrieved image are set to Null. The ratio of color values is also transmitted to the server 200 .

Further, step S300 also includes:

If the first color value of the retrieved image received by the server 200 is not Null, the following operations are performed for each APP icon among the M icons stored in the first storage module:

S301. If the absolute value of the difference between the first color value of the retrieved image transmitted by the mobile terminal 300 and the first color value of the compared APP icon exceeds the third threshold, process the next APP icon; otherwise, perform S302;

S302. If the ratio of the first color value of the retrieved image transmitted by the mobile terminal 300 to the first color value of the compared APP icon is lower than the fourth threshold, process the next APP icon; otherwise, perform S303;

S303. Search the first storage module according to the received search image, obtain a second search result and send it to the mobile terminal. The second search result represents the similarity between the icon and the input image. Greater than the second set threshold, the second search result includes a low-resolution APP icon, APP-ID and similarity.

That is to say, in this step, when the first color value of the received retrieved image is not Null, the server 200 will compare the received first color value of the retrieved image with the M stored in the first storage module. The first color values of the APP icons are compared in order, that is, starting from the first one. If the difference between the first color values of the two compared icons exceeds the third threshold, compare the second one and keep comparing. to M, if the difference between the two does not exceed the third threshold, then the ratio of the first color value of the received retrieved image to the ratio of the first color value of the M APP icons stored in the first storage module is Comparisons are performed sequentially, that is, starting from the first one. If the ratio of the first color value of the two compared icons is lower than the fourth threshold, then compare the second one, and continue to compare to M. If both is not lower than the fourth threshold, then the search is performed in the first storage module according to the received search image, and the second search result is obtained and sent to the mobile terminal. The icon represented by the second search result is the same as the fourth threshold. The similarity of the input image is greater than the second set threshold, and the second search result includes the low-resolution APP icon, APP-ID and similarity. In this way, the corresponding APP icon can be retrieved more accurately. In the embodiment of the present invention, the third threshold can be set to a threshold that a person skilled in the art can clearly distinguish between the first color value and the second color value. The present invention is not particularly limited. For example, for 24-bit RGB, the third threshold can be is {26,26,26}. The fourth threshold may be 1/2.

In this embodiment, since the first color value and the second color value of the APP icon are used for retrieval, the accuracy of retrieval can be further improved.

In summary, in the APP icon retrieval system provided by the embodiment of the present invention, the server side stores millions of M APPs that are far smaller than the number of general images, and the ranking selection is based on the total download volume and update download volume of the M APPs. The number of K APPs is much smaller than M, and updating these APPs in real time can reduce the image storage space and ensure that the stored APPs are as new and accurate as possible. The terminal database of the mobile terminal stores the same APPs as the K (for example, several hundred) APPs stored on the server side which are far less than M in number, because these K APPs are ranked according to the total downloads and update downloads of the APPs. The selection is made so that these K APPs are commonly used APPs, which can meet the retrieval needs of commonly used APPs. Users can directly search on mobile terminals, which can improve the speed and accuracy of retrieval.
