Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of an APP icon update system according to an embodiment of the present invention. As shown in fig. 1, the APP icon update system provided by the embodiment of the present invention includes a server side 101 and a mobile terminal 102 that perform information interaction. The server 101 is configured to download APP icons and APP information of M APPs from the plurality of third party servers 105, store the downloaded APP icons and APP information in the server database 103, update the M APPs stored in the server database 103 according to a preset update period, and store K APPs with top downloading amounts of M APPs in the cache 104, where the K APPs are a union of top K1 APPs ordered according to a total downloading amount in the plurality of third party servers 105 and top K2 APPs ordered according to an update downloading amount in the plurality of third party servers 105 within a set time, for example k1=500, that is, top 500 APPs from a date of APP distribution to a current total downloading amount in the plurality of third party servers, for example k2=200, that is, top 200 APPs with updated downloading amounts in the plurality of third party servers within the preset update period, for example, within three days recently; the APP information comprises an ID of the APP, a name of the APP, a developer, a version number, a brief introduction and an APP downloading amount. K APP are stored in a terminal database of the mobile terminal 102, wherein the K APP comprise K3 APP ordered according to total downloading amount and K4 APP ordered according to updating downloading amount, and the K APP in the terminal database are updated according to a preset updating mode, so that the K APP in the terminal database are identical to the K APP in the server database; wherein M is more than or equal to 100 ten thousand; k is much smaller than M.
Specifically, the server side 101 may crawl APP icons and APP information from a plurality of, for example, N third party servers 105 through a crawler, where the APP information includes an ID of APP, a name of APP, a developer, a version number, a profile, an APP download amount, and the like. Basically, the APP information, APP icons and image feature values of the icons of M APPs can be obtained by downloading the commonly used application shops such as the hua, millet, OPPO, pea pod, apple application shops, google and the like once. In one example, the server side 101 pre-processes (e.g., merges according to the APP ID, etc.) the APP icon and APP information and stores the pre-processed APP icon and APP information in the server database 103. The server side 101 downloads the APP icons and APP information at regular time (e.g., daily) and updates the server database 103, so that M APPs and K APPs can be ensured to be updated in time, so that the stored APPs are as accurate as possible.
In embodiments of the present invention, K1 may be greater than or equal to five parts per million of M and K2 may be greater than or equal to two parts per million of M.
In the embodiment of the present invention, the mobile terminal 102 may keep synchronization with the server side 101 in two ways:
example 1
In this embodiment, the mobile terminal 102 may remain synchronized with the server side 101 by:
a. the mobile terminal 102 sends an APP-ID list of the mobile terminal to the server side 101;
b. the server 101 compares the APP-ID list sent by the mobile terminal 102 with its current APP-ID list to obtain an APP-ID list to be added and an APP-ID list to be deleted by the mobile terminal 102, and sends corresponding APP icons and APP information to the mobile terminal 102 according to the obtained lists;
c. the mobile terminal 102 adds and deletes corresponding APP icons and APP information in the terminal database according to the APP-ID list to be added and the APP-ID list to be deleted, thereby maintaining synchronization with the server side 101.
In this embodiment, the mobile terminal 102 and the server side 101 synchronize by transmitting the APP-ID list, so that the APP between them can be completely synchronized.
Example 2
In this embodiment, the mobile terminal 102 may remain synchronized with the server side 101 by:
1. the mobile terminal 102 sends its APP icon update information to the server 101, where the update information includes a time T1 of last update of the mobile terminal, and t1=null means that the mobile terminal is not updated for the first time;
2. the server 101 obtains updated APP icons and APP information in K APPs in a time period from T0 to T1 according to the received time T1 and the current time T0, and sends the updated APP icons and APP information to the mobile terminal 102, where the APP information further includes a time T2 when the APP has been updated recently; time T2 is used to indicate the time that APP was last present in K, e.g., T2 for WeChat APP can be very long. For example, t1=2 months 10 days, t0=3 months 25 days, then, based on T2 of K APPs on 3 months 25 days, APP with T2 between 2 months 11 days to 3 months 25 days is acquired, and the acquired APP is newly added APP.
In another example, the APP information sent by the server side 101 further includes: the KF1 marks and the KF2 marks of K1 and K2, wherein KF1 is equal to 1 to identify that the corresponding APP-ID belongs to the APP in the K1 APP, and KF2 is equal to 1 to identify that the corresponding APP-ID belongs to the APP in the K2 APP.
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 APP charts and APP information in the corresponding K3 APPs and K4 APPs from the terminal database, including:
(1) Determining the number K5 and K6 of the APP with KF1 equal to 1 and KF2 equal to 1 according to the received updated APP icons and APP information;
(2) The last K5 APP of the K3 APP is replaced by the determined K5 APP, and the last K6 APP of the K4 APP is replaced by the determined K6 APP.
For example, 6 APPs in the server side 101 are updated, where 2 kf1=1 and kf2=0; 1 kf1=0, kf2=1; the remaining 3 kf1=1, kf2=1. Then the mobile terminal 102 will replace 5 of kf1=1 with the last 5 of the total download amounts K3 and 1 of kf2=1 with the last 1 of the updated download amounts K4 according to the received APP information.
In embodiment 2, compared with embodiment 1, the mobile terminal 102 only transmits the update time T1 to the server side 101, so that the traffic of the server side 101 can be reduced.
According to the APP icon updating system provided by the embodiment of the invention, the server side stores M APP and K APP with the ranking selection number far smaller than M according to the total download amount and the updating download amount in the M APP, and updates the APP in real time, so that the stored APP is ensured to be as new and accurate as possible, and the APP which is the same as the K APP stored in the server side is stored in the terminal database of the mobile terminal, thereby enabling the APP stored in the mobile terminal to be up-to-date, facilitating the user to search the APP icon and ensuring the searching accuracy.
Fig. 2 is a schematic structural diagram of an APP icon retrieval system according to another embodiment of the present invention. As shown in fig. 2, the APP icon retrieval system provided by the embodiment of the present invention includes a server side 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, where the read-write speed of the second storage module 202 is greater than the read-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 module 202 stores K APPs of M APPs, where the K APPs are a union of the first K1 APPs ordered according to the total downloading amount and the first K2 APPs ordered according to the updated downloading amount within a set time, M is greater than or equal to 100 ten thousand, K is far less than M, for example k1=500, that is, the first 500 APPs from the date of APP distribution to the current total downloading amount, for example k2=200, that is, the first 200 APPs of the updated downloading amount within a predetermined update period, for example, within the last three days; the updating module 203 is configured to update the APP stored in the first storage module 201 according to a preset updating period; the APP information comprises an APP ID, an APP name, a developer, a version number, a profile and an APP downloading amount; the terminal database of the mobile terminal 300 stores K APPs identical to 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 those in the previous embodiment, that is, the manner in which the server 200 downloads and updates the APP is the same as that of the server 101 in the previous embodiment, and the manner in which the mobile terminal 300 and the server 200 keep synchronization is the same as that in the previous embodiment, so that detailed descriptions thereof are omitted for avoiding redundant descriptions.
In embodiments of the present invention, K1 may be greater than or equal to five parts per million of M and K2 may be greater than or equal to two parts per million of M.
In the embodiment of the invention, when a user needs to search the APP icon, the search system executes the following operations:
s100, the mobile terminal 300 obtains an image of the APP icon which is required to be searched by the user, wherein the image comprises an icon area which is designated to be searched by the user.
First, the user takes a picture using the mobile terminal 300 to obtain an image including an APP icon, and then, the user operates the mobile terminal 300 to select an icon area desired to be searched in the image, i.e., to designate the searched icon area, with a square frame. Alternatively, the APP icon is directly selected with a square frame when photographing, and the icon area desired to be retrieved is obtained.
S200, the mobile terminal 300 searches the icon area designated for searching in the terminal database as a searching image to obtain a first searching result, and if the similarity between the icon represented by the first searching result and the searching image is larger than a first set threshold value, the first searching result is displayed to the user; otherwise, the search image is sent to the server 200.
The mobile terminal 300 takes the image in the dashed box as the image input by searching (searching in the terminal database), preferably, the mobile terminal 300 extracts the characteristic value of the image and searches in the terminal database based on the extracted characteristic value, if the better result is searched, the image is directly presented to the user, if the better result is not searched, the image is transmitted to the server side, in another example, the characteristic value of the image is transmitted to the server side 200, the transmitted data amount can be greatly reduced by using the characteristic value, namely, the flow is reduced.
And S300, the server 200 searches in the first storage module 201 according to the received search image to obtain a second search result and sends the second search result to the mobile terminal 300, wherein the similarity between the icon represented by the second search result and the search image is greater than a second set threshold, and the second search result comprises an APP icon with low resolution, an APP-ID and similarity.
The server 200 performs searching among the million APP icons according to the received search image (the feature value of the preferred image), and returns a search result with similarity greater than a second set threshold, that is, a second search result, to the mobile terminal 300. The second search result may include the low resolution APP icon, APP-ID and similarity, optionally, APP name and developer, but not other information such as profile. The first set threshold and the second set threshold may be the same, preferably the first set threshold < the second set threshold to reduce network traffic. The low resolution may be LDPI (Low Density Screen,120 DPI) with an icon size of 36x 36px.
And S400, the mobile terminal 300 sorts the received low-resolution APP icons according to the similarity and displays the icons in an icon block mode.
S500, the mobile terminal 300 receives an icon block (for example, clicking) selected by a user, and searches and displays a corresponding APP icon and APP information in the first storage module by using a corresponding APP-ID; and
s600, the mobile terminal 300 adds the APP-ID and APP information of the icon block clicked by the user into the terminal database.
The APP icon retrieval system provided by the embodiment of the invention has the following technical effects:
(1) Characteristics of APP icon: 1) The resolution is far lower than that of a common image, the xhdpi is less than 10000 pixels, and the resolution is far lower than 2000 ten thousand pixels of the common image; 2) The number of APP icons is in the millions, which is far less than the number of general images;
(2) The mobile terminal only stores hundreds of APP icons, the occupied space is small, and image processing and searching can be directly completed at the mobile terminal;
(3) The common hundreds of APP icons are all arranged on the mobile terminal, so that on one hand, the shot images hit in the mobile terminal have extremely high probability, and on the other hand, the communication flow with the server side is reduced;
(4) The user operation is convenient, only needs to take a picture, and the instantaneity is good.
Further, in the embodiment of the present invention, the first storage module 201 further stores a first color value of the APP icon and a proportion of pixels of the first color value to all pixels of the image, where the first color value is a value of the most color of the APP icon. For example APP of a civil bank, the main color is white, so the first color value is "white", accounting for 70%.
Further, step S200 further includes:
s201, the mobile terminal 300 acquires a first color value and a second color value of a search image, and the proportion of pixels of the first color value and the second color value of the search image to all pixels of the search image, wherein the first color value and the second color value are the values of the most color of the search image and the next most color of the search image respectively;
s202, if the mobile terminal 300 determines that the ratio of the first color value of the search image is greater than the first threshold, for example, 30%, and the ratio of the first color value of the search image to the second color value exceeds the second threshold, for example, 2, then the ratio of the first color value of the search image and the first color value is also transmitted to the server 200, otherwise, the first color value of the search image is set to Null, and then the ratio of the first color value of the search image and the first color value is also transmitted to the server 200.
Further, step S300 further includes:
if the first color value of the search image received by the server 200 is not Null, the following operations are performed for each APP icon in the M icons stored in the first storage module:
s301, if the absolute value of the difference between the first color value of the search image transmitted by the mobile terminal 300 and the first color value of the compared APP icon exceeds a third threshold value, processing the next APP icon; otherwise, S302 is performed;
s302, if the ratio of the first color value of the search image transmitted by the mobile terminal 300 to the ratio of the first color value of the compared APP icons is lower than a fourth threshold value, processing the next APP icon; otherwise, S303 is performed;
s303, searching in the first storage module according to the received search image to obtain a second search result, and sending the second search result to the mobile terminal, wherein the similarity between the icon represented by the second search result and the input image is larger than a second set threshold, and the second search result comprises an APP icon with low resolution, an APP-ID and the similarity.
That is, in this step, the server 200 sequentially compares the first color value of the received search image with the first color values of the M APP icons stored in the first storage module when the first color value of the received search image is not Null, that is, from 1 st, if the difference between the first color values of the two icons exceeds the third threshold, then compares 2 nd until M, if the difference between the two color values does not exceed the third threshold, then sequentially compares the proportion of the first color value of the received search image with the proportion of the first color value of the M APP icons stored in the first storage module, that is, from 1 st, if the proportion of the first color value of the two icons compared is lower than the fourth threshold, then compares 2 nd until M, if the proportion of the two icons is not lower than the fourth threshold, then searches in the first storage module according to the received search image, obtains a second search result, and sends the second search result to the mobile terminal, if the difference between the two color values does not exceed the third threshold, then compares the proportion of the first color value of the two icons with the first color value of the M APP icons stored in order, that the proportion of the first color value of the M APP icons is lower than the fourth threshold, and the second color value of the first color value is similar to the M, and the second color value, and the APP icon is more similar to the second ID. In the embodiment of the present invention, the third threshold may be set to be a threshold that can be clearly distinguished between the first color value and the second color value by a person skilled in the art, and the present invention is not particularly limited, and for example, the third threshold may be {26,26,26} for 24 bits of RGB. 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 searching, the accuracy of searching can be further improved.
In summary, in the APP icon retrieval system provided by the embodiment of the invention, the server side stores M APPs with the number far smaller than the number of the general images and K APPs with the number far smaller than M according to the ranking selection of the total download amount and the update download amount of the M APPs, and updates the APPs in real time, so that the image storage space can be reduced, and the stored APPs can be ensured to be new and accurate as much as possible. The terminal database of the mobile terminal stores K (for example, hundreds) of APP which are stored in the same quantity as the server and are far less than M, and the K APP is selected according to the ranking of the total downloading quantity and the updated downloading quantity of the APP, so that the K APP is a common APP, the search requirement of the common APP can be met, and a user can search directly at the mobile terminal, and the search speed and accuracy can be improved.
The above examples are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, but it should be understood by those skilled in the art that the present invention is not limited thereto, and that the present invention is described in detail with reference to the foregoing examples: any person skilled in the art may modify or easily conceive of the technical solution described in the foregoing embodiments, or perform equivalent substitution of some of the technical features, while remaining within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention, and are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
