The service scene applied by the two-dimensional code generally comprises: information acquisition, website skipping, anti-counterfeiting tracing, advertisement pushing, preferential promotion, payment, account login and other different business scenes.
However, the precondition that two-dimensional codes can be applied to these business scenarios is: two-dimensional codes need to be placed in these business scenarios. Specifically, a two-dimensional code applied to a service scene is inserted into a carrier corresponding to the service scene. For example: in a business scene of advertisement pushing, a two-dimensional code containing product information is required to be inserted into an advertisement related to the product, and if the advertisement related to the product is a poster, the two-dimensional code containing the product information is pasted at a corresponding position of the poster. Thus, after the advertisement corresponding to the product is pushed, if the user is interested in the product displayed in the advertisement, the relevant information of the product can be obtained by scanning the two-dimensional code.
However, at present, a two-dimensional code is inserted into a carrier corresponding to a service scene, and the two-dimensional code is usually copied and pasted into the carrier corresponding to the service scene in a manual mode, so that the processing efficiency of the two-dimensional code is low.

That is, the subject content of the target image and the area occupied by the subject content can be determined by the image recognition technology, and then, in the target image, other areas except the area occupied by the subject content of the target image can be used as the usable area.
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the technical solutions of the present specification will be clearly and completely described below with reference to specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
Fig. 1 is a flow chart of a two-dimensional code processing method according to an embodiment of the present disclosure. The method may be as follows.
And step 101, receiving a target image sent by a user and a two-dimensional code to be processed.
In the embodiment provided in the present specification, when a user needs to embed a two-dimensional code into a target image, the target image and the two-dimensional code to be embedded may be sent to a two-dimensional code processing device, and at this time, the two-dimensional code processing device receives the target image and the two-dimensional code to be embedded, which are sent by the user.
The target image may be one or a plurality of target images. Similarly, the two-dimensional code to be embedded may be one or more. The number of the target images and the two-dimensional codes to be embedded is not limited here. An example of embedding a two-dimensional code into a target image will be described below.
Step 103: and identifying the content contained in the target image based on an image identification technology.
In the embodiment provided in the present disclosure, since some target images may reserve an area in the design stage, where the reserved area is used for embedding a two-dimensional code, when receiving a target image sent by a user, a reserved area detection operation is started first, that is, whether the target image includes a preset identifier area is detected.
Specifically, the features contained in the target image are extracted, the extracted features are compared with preset identification features, and whether the target image contains a preset identification area or not is judged according to a comparison result. If the extracted features are consistent with the preset identification features as a result of the comparison, the target image is indicated to contain a preset identification region; if the extracted features are inconsistent with the preset identification features, the target image is indicated to not contain the preset identification region.
The identification area described herein may be an area including a predetermined identification feature. The preset identifying feature herein may be understood as a feature of a specified shape, such as: square boxes, may also be features of a specified shape that appear at a specified location, such as: square box in the lower right corner of the target image.
If the preset identification feature is a square frame at the right lower corner of the target image, when the target image sent by the user is received, the right lower corner of the target image is positioned, the feature at the right lower corner is further extracted, the extracted feature is compared with the preset identification feature, and whether the target image contains the preset identification region or not is judged according to the comparison result. If the extracted features are consistent with the preset identification features as a result of the comparison, the target image is indicated to contain a preset identification region; if the extracted features are inconsistent with the preset identification features, the target image is indicated to not contain the preset identification region.
And secondly, if the target image does not contain the preset identification area, identifying the salient area contained in the target image based on an image identification technology, wherein the salient area contains one or more of a character area and a pattern area.
Specifically, whether characters are contained in the target image is identified by using an EAST model, and if the identification result is that the characters are contained, the identified area where the characters are located is determined to be a salient area contained in the target image.
And identifying whether the pattern is contained in the target image by using an OpenCV saliency detection algorithm, and if the identification result is that the pattern is contained, determining the area where the identified pattern is located as a saliency area contained in the target image. The pattern region is understood to be a region containing an icon, and is understood to be a region containing a background pattern, or the like.
The pattern area here is different from the pattern included in the preset identification area described above.
Step 105: and determining a usable area from the target image according to the identification result.
The usable area is other areas of the target image except for the area occupied by the subject content of the target image.
In the embodiment provided in the present specification, since it is determined that the target image does not include the preset identification area through the reserved area detection operation, the usable area is determined from the other areas of the target image than the significant area according to the identified significant area.
Specifically, first, according to the identified salient region, using a specified shape detection algorithm, dividing other regions except the salient region in the target image into at least one region to be selected, wherein the shape of the region to be selected is the specified shape.
Assuming that the specified shape is rectangular, the region other than the salient region in the target image may be divided into a plurality of rectangular regions to be selected, which have different region sizes, using a maximum rectangular detection algorithm.
And secondly, determining the position, the area size and the color of each region to be selected for each region to be selected.
Specifically, based on an image coordinate system established by the target image, determining coordinates of pixel points contained in the candidate area and pixel values of the pixel points;
Determining the position of the region to be selected according to the coordinates of the pixel points; calculating the area size of the region to be selected according to the coordinates of the contained pixel points; and determining the color of the region to be selected according to the pixel value of the contained pixel point.
And finally, screening available areas from the determined areas to be selected according to the positions, the area sizes and the colors of the areas to be selected.
Specifically, for each candidate region, determining a candidate weight corresponding to the candidate region according to the position, the area size and the color of the candidate region, wherein the candidate weight is used for representing the probability size of selecting the candidate region as a usable region.
It should be noted that, when determining the weight to be selected corresponding to the area to be selected, the area size of the area at least needs to meet the minimum value of the two-dimensional code picture, that is, the closer the area size is to the minimum value of the two-dimensional code picture, the larger the weight to be selected of the area to be selected is; the closer the position is to the edge of the target image, the larger the weight value to be selected of the region to be selected is; the larger the color difference between the color and the color of the salient region, the larger the weight value to be selected of the region to be selected.
Specifically, for each region to be selected, sorting the regions to be selected according to the difference between the area size of the region and the minimum value of the set two-dimensional code picture, wherein the smaller the difference is, the more forward the sorting is, and at the moment, determining the weight value of the area size for each region to be selected according to the sorting result;
For each region to be selected, determining a weight value of the position of each region to be selected according to the position of the region, wherein the closer the position of the region is to the edge weight value of the target image, the larger the position of the region is;
and determining the weight value of the color of each candidate region according to the color of the region and the theme color of the target image for each candidate region, wherein the weight value is larger as the color difference between the color of the region and the theme color of the target image is larger.
And finally, calculating the weight to be selected of each area to be selected according to the weight value of the area size, the weight value of the position and the weight value of the color of each area to be selected. Wherein the specific gravity of the weight value of the area size is greater than that of the weight value of the position; the specific gravity of the weight value of the position is greater than that of the color.
For example: the candidate weight of the candidate region=w1+w2+l+w3+c, wherein W1 is greater than W2; w2 is larger than W3, and S represents a weight value corresponding to the area size; l represents a weight value corresponding to the position; c represents the weight value corresponding to the color.
And after the candidate weights of the candidate areas are obtained, screening available areas from the determined candidate areas according to the candidate weights of the candidate areas. Namely selecting the selected area with large weight value as the screened usable area.
Step 107: and adding the two-dimensional code to be processed to the usable area, and storing a target image containing the two-dimensional code to be processed.
In the embodiment provided in the specification, after screening out usable areas from the determined candidate areas, creating a picture frame in the usable areas; judging whether the size of the picture frame is matched with the size of the two-dimensional code to be processed or not; if so, adding the two-dimensional code to be processed into the picture frame; if the two-dimensional codes are not matched, a prompt message is sent to the user, the adjusted two-dimensional codes to be processed, which are sent by the user, are received, and the adjusted two-dimensional codes to be processed are added into the picture frame; the prompting message comprises a size parameter of the picture frame.
Specifically, after screening the usable area from the determined candidate areas, comparing the area value of the usable area with the area value of the two-dimensional code to be processed;
if the area value of the usable area is larger than the area value of the two-dimensional code to be processed, creating a picture frame in the usable area, and judging whether the size of the picture frame is matched with the size of the two-dimensional code to be processed; if so, adding the two-dimensional code to be processed into the picture frame; if the two-dimensional codes are not matched, a prompt message is sent to the user, the adjusted two-dimensional codes to be processed, which are sent by the user, are received, and the adjusted two-dimensional codes to be processed are added into the picture frame; the prompting message comprises a size parameter of the picture frame.
If the area value of the usable area is larger than the area value of the two-dimensional code to be processed, a picture frame is created in the usable area, and at this time, a picture frame matched with the size of the two-dimensional code to be processed can be created directly according to the area value of the two-dimensional code to be processed, so that the two-dimensional code to be processed is directly added into the picture frame.
If the area value of the usable area is not larger than the area value of the two-dimensional code to be processed, creating a maximum picture frame in the usable area, and then judging whether the size of the picture frame is matched with the size of the two-dimensional code to be processed; if so, adding the two-dimensional code to be processed into the picture frame; if the two-dimensional codes are not matched, a prompt message is sent to the user, the adjusted two-dimensional codes to be processed, which are sent by the user, are received, and the adjusted two-dimensional codes to be processed are added into the picture frame; the prompting message comprises a size parameter of the picture frame.
Optionally, if it is determined in step 103 that the target image includes a preset identified area through a reserved area detection operation, the preset identified area is determined as a usable area; and further, the two-dimensional code to be processed is added to the preset identification area, and a target image containing the two-dimensional code to be processed is stored.
Here, the method of adding the two-dimensional code to be processed to the preset identification area is similar to the method of adding the two-dimensional code to be processed to the usable area, and will not be described in detail.
Based on the technical method provided by the specification, a target image sent by a user and a two-dimensional code to be processed are received; identifying content contained in the target image based on an image identification technique; determining a usable area from the target image according to the identification result; and adding the two-dimensional code to be processed to the usable area, and storing a target image containing the two-dimensional code to be processed.
For a target image to be added with the two-dimensional code, a usable area for adding the two-dimensional code is determined from the target image through an image recognition technology, and then the two-dimensional code is added into the target image by utilizing a two-dimensional code adding technology, so that the processing efficiency of the two-dimensional code is improved on one hand, and on the other hand, the two-dimensional code can be accurately embedded into a proper position of the target image.
Based on the same inventive concept, fig. 2 is a schematic flow chart of a two-dimensional code processing method provided in the present specification. The method may be as follows.

Step 209: and determining a usable area from other areas except the salient area in the target image according to the identified salient area.
Step 211: a largest picture frame is created in the usable area.

Of course, other implementations, such as logic devices or combinations of hardware and software, are not excluded from the present description, that is, the execution subject of the following processing flows is not limited to each logic unit, but may be hardware or logic devices.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component.
