Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a method provided in an embodiment of the present application. The flow is applied to the first electronic device. As an embodiment, the first electronic device is a front-end device. Optionally, the front-end device is a device for capturing images, such as a camera or the like.
As shown in fig. 1, the process may include the following steps:
In application, the first electronic device may periodically or periodically acquire the original image. Alternatively, the original image may be an image in YUV format (YUV image for short). In YUV format, Y represents brightness (Luma) and U, V represents Chroma (Chroma or Chroma) for describing color and saturation (for characterizing color).
After the first electronic device acquires the original image, the first electronic device acquires a first original image to be transmitted to the second electronic device for image processing from the acquired original image according to a configured analysis algorithm. Taking an original image as a captured face image as an example, after a first electronic device acquires a face original image, it acquires a first original image to be transmitted to a second electronic device for image processing from the acquired face original image according to a configured face capture analysis algorithm, for example, selects a face original image with good image quality (the face capture analysis algorithm can analyze the image quality) as the first original image; or, the original image of the face with the front face is selected as the first original image and the like. That is, the first original image to be transmitted to the second electronic device for image processing is finally obtained in step 101.
In this embodiment, the second electronic device may be a backend device. Optionally, the backend device is a device for performing image processing on an original image acquired by the front-end device, such as a Network Video Recorder (NVR), a Digital Video Recorder (DVR), and the like.
It should be noted that the image processing in step 101 may be generally referred to as any image processing. For example, when the original image is a face image, the image processing may be face recognition processing; when the original image is a human body image, the image processing can be human body identification processing; when the original image is a vehicle image, the image processing may be vehicle identification processing or the like, and the present embodiment is not particularly limited.
And 102, carrying the target original image at the specified position of the coded image, and transmitting the coded image to the second electronic device, wherein the coded image is an image obtained by coding the first original image.
Here, the target original image may be any original image that needs to perform the above-mentioned image processing, and for example, may be the first original image or a partial image area in the first original image, or other original images to be processed and the first original image, and so on.
Optionally, in an example, the target original image may be related to the first original image, for example, the target original image may be the first original image or a partial image area in the first original image, or the first original image may be obtained as described in the following step a, which is not limited herein.
As an embodiment, the target original image is determined by the following step a:
a, performing first processing on a first original image to obtain a second original image; the first processing is used for enabling the second original image to meet the image requirement when the second electronic equipment executes the image processing; and determining the target original image according to the second original image.
Alternatively, in order to ensure that the second electronic device smoothly executes the image processing, such as the face recognition processing, the image requirements of the second electronic device for executing the image processing, such as the face recognition processing, and the like, may be configured in advance according to actual requirements. Therefore, the substantial first processing performed on the first original image in step a is optimization processing of the first original image, and the purpose of the first processing is to make the second original image obtained after the optimization processing meet the image requirements of the second electronic device for performing the image processing, such as face recognition processing and the like.
As to how to process the first original image in step a, it is not particularly limited on the premise that the second original image obtained after the processing meets the image requirements of the second electronic device for performing the above-mentioned image processing, such as face recognition processing and the like. For ease of understanding, fig. 3 below illustrates one embodiment, and the description is omitted here for the sake of brevity.
In addition, in step a, how to determine the target original image according to the second original image is described in detail below, and details are not repeated here.
In one example, the image file format of the encoded image is a JPEG format. JPEG (joint photographic Experts group), a standard for compression of continuous tone still images, is made by the international organization for standardization (ISO), and the JPEG format is currently the most commonly used image file format with the suffix name of jpg or JPEG.
In the JPEG format, 15 areas (called custom data areas for short) for the custom use of the application program are reserved, the mark codes of the 15 custom data areas are 0xFFE1-0xFFEF, the content of the area can be added by the application, and the price code of the coded image is not influenced. Based on this, as an embodiment, the specified position may be at least one reserved custom data area in JPEG format.
In the present embodiment, the format and the designated position of the encoded image are merely examples, and are not intended to limit the present application. The embodiment only needs to ensure that the target original image is carried at the designated position of the coded image and transmitted to the second electronic device.
Thus, the flow shown in fig. 1 is completed.
As can be seen from the flow shown in fig. 1, in the present application, the first electronic device carries the target original image at the designated position of the encoded image and sends the target original image to the second electronic device, so that the second electronic device can directly obtain the target original image from the designated position of the encoded image and process the target original image, and perform image processing on the original image.
Further, in the application, the target original image meeting the image requirement of the second electronic device when executing image processing is obtained by performing the first processing on the first original image, which further ensures the effect of the second electronic device in performing the image processing on the target original image.
Referring to fig. 2, fig. 2 is a flowchart of a second image processing method according to an embodiment of the present application. The process is applied to the first electronic device.
As shown in fig. 2, the process may include the following steps:
This step 201 is similar to the step 101, and is not described herein.
Step 202 is similar to step a described above and will not be described here.
This step 203 is similar to the step 102 described above and will not be described here.
Thus, the flow shown in fig. 2 is completed.
Through the process shown in fig. 2, the first electronic device can carry the target original image at the designated position of the encoded image and send the target original image to the second electronic device, so that the second electronic device can directly obtain the target original image from the designated position of the encoded image and process the target original image, and perform image processing on the original image.
Further, in the application, the target original image meeting the image requirement of the second electronic device when executing image processing is obtained by performing the first processing on the first original image, which further ensures the effect of the second electronic device in performing the image processing on the target original image.
The first processing performed on the first original image in step a or step 202 is described below:
referring to fig. 3, fig. 3 is a flowchart illustrating implementation of a first process performed on a first original image according to an embodiment of the present application. As shown in fig. 3, the process may include the following steps:
Taking the first original image as a face image as an example, the third original image may be an image region of the first original image that includes a face (i.e., a target object) and has a specified size. The specified dimensions can be determined according to actual requirements, and can be, for example: a region that completely includes the face and is redundant by 2 centimeters (cm) up, down, left, and right.
As an example, in the first implementation, the step of the third original image not satisfying the image requirement when the second electronic device performs the image processing may include: the brightness of the third original image is lower than the image brightness requirement required when the second electronic device executes the image processing.
Accordingly, in step 302, when the brightness of the third original image is lower than the image brightness requirement required when the second electronic device executes the image processing, the first processing may be a brightening processing for enhancing the brightness so that the finally obtained brightness of the second original image meets the image brightness requirement when the second electronic device executes the image processing.
As an example, in the second implementation, the step of the third original image not satisfying the image requirement when the second electronic device performs the image processing may include: the outline of the third original image and/or the edge of the third original image and the region of the gray jump do not meet the requirement of image definition when the second electronic equipment executes the image processing.
Based on this, in this step 302, when the contour and/or the edge and the grayscale jump area of the third original image do not satisfy the requirement of the second electronic device for image sharpness when executing the image processing, the first processing is sharpening. And the sharpening process is used for compensating the contour and/or enhancing the edge and the gray level jump area so that the finally obtained contour and/or edge and gray level jump area of the second original image meet the image definition requirement when the second electronic device executes the image processing.
As an example, in the third embodiment, the third original image not satisfying the image requirement when the second electronic device performs the image processing includes: the resolution of the third original image is not the resolution required when the second electronic device performs the image processing.
Accordingly, in step 302, when the resolution of the third original image is not the resolution required by the second electronic device to execute the image processing, the first processing is configured to process the resolution of the third original image so that the resolution of the finally obtained second original image is the resolution required by the second electronic device to execute the image processing.
In one example, the resolution of the third raw image that is not required for the second electronic device to perform the image processing may include: the image size of the third original image is relatively large, for example, much larger than the set size. Here, the set size may be an image size required when the second electronic device performs the image processing. Based on this, the processing the third original image so that the resolution of the processed third original image is the resolution required by the second electronic device when executing the image processing may include: the third original image is appropriately scaled to a size that may approximate the set size, e.g., 100 x 100.
In another example, the resolution of the third raw image that is not required for the second electronic device to perform the image processing may include: the image size of the third original image is relatively small, e.g. much smaller than the set size. Here, the set size may be an image size required when the second electronic device performs the image processing. Based on this, the processing the third original image so that the resolution of the processed third original image is the resolution required by the second electronic device when executing the image processing may include: the third original image is suitably expanded to a size that may approximate the set size, e.g., 100 x 100.
It should be noted that, the above describes, by taking the first embodiment to the third embodiment as an example, the first process corresponding to the case where the third original image does not satisfy the image requirement when the second electronic device executes the image process, which is only an example for making the present embodiment clearer and is not a limitation. In an example, any combination of the first embodiment to the third embodiment may also occur, or other embodiments may also occur, but it is only necessary to finally ensure that the obtained second original image meets the image requirement when the second electronic device executes the image processing, and this embodiment is not described in detail again.
The flow shown in fig. 3 is completed.
The first processing on the first original image in step a or step 202 described above is realized by the flow shown in fig. 3. It should be noted that the flow shown in fig. 3 is only an exemplary description for making the first processing performed on the first original image in step a or step 202 clear, and is not limited. For example, other approaches may also be used: the third original image is no longer extracted from the first original image, but the first original image is directly processed when the first original image does not meet the image requirement when the second electronic device executes the image processing, and this embodiment is not described in detail by way of example.
The following describes determining the target original image according to the second original image in step a or step 202:
in one example, there are many implementations for determining the target original image according to the second original image, such as determining the second original image as the target original image; or, performing second processing on the second original image to obtain a fourth original image, and determining the fourth original image as the target original image.
Here, the second processing is to suppress the second original image from being falsified or misread to improve the security of the second original image. As an embodiment, the second process here may be an encryption process. Based on this, the second processing the second original image to obtain the fourth original image may include: and encrypting the second original image according to a set encryption algorithm.
Alternatively, the encryption algorithm may be a set image data obfuscation algorithm such as a data processing algorithm such as filtering interpolation. Taking the encryption algorithm as the set image data obfuscation algorithm as an example, the set image data obfuscation algorithm may be used to perform obfuscation processing on the image data in the second original image. Namely, the encryption of the second original image is realized, so that the second original image is prevented from being tampered or misread, and the security of the second original image is improved.
Optionally, performing obfuscation processing on image data in the second original image at least includes: and modifying the designated parameters of the pixel points in the second original image. In one example, specifying parameters includes at least: color values and/or grayscale values.
Taking the designated parameter as the color value as an example, modifying the designated parameter of the pixel point in the second original image may be: and modifying the color value of the pixel point in the second original image, for example, modifying the color value of a certain pixel point in the second original image from a first color value for representing red (R) to a second color value for representing blue (R).
The above describes how the target original image is determined from the second original image in step a or step 202.
The following describes an image processing method provided by an embodiment of the present application in terms of the opposite end of the first electronic device (denoted as a second electronic device):

As described above, the second original image is an image obtained by performing the first processing on the first original image, and the first processing is used to make the second original image satisfy the image requirement when the second electronic device executes the image processing.
As another embodiment, the target original image is an image obtained by performing the second processing on the second original image. As described above, the second process is used to suppress the second original image from being tampered or misread, so as to improve the security of the second original image, for example, the second process may be an encryption process or the like.
Based on this, the performing of the corresponding image processing on the target original image in step 402 may include: and performing third processing corresponding to the second processing on the target original image to obtain a second original image, and performing corresponding image processing on the second original image.
In one example, the third process is a reverse process of the second process, for example, if the second process is an encryption process, the third process is a corresponding decryption process. The encryption processing can be realized according to a corresponding encryption algorithm, and the decryption processing can be realized according to a decryption algorithm corresponding to the encryption algorithm. As an embodiment, the encryption algorithm and the decryption algorithm are the same set of encryption and decryption algorithms. In one example, to ensure that the first electronic device and the second electronic device cooperatively perform image processing, the encryption algorithm used by the first electronic device and the decryption algorithm used by the second electronic device may be recommended to be the same company or to be cooperatively issued with the same set of encryption and decryption algorithms used inside.
In this embodiment, there are many ways to process the image in step 402, such as: in one example, the first original image is a captured face image; accordingly, the above image processing is face recognition processing. For another example, in one example, the first original image is a human body image, and accordingly, the image processing may be human body recognition processing. For another example, in one example, the first original image is a vehicle image, and accordingly, the image processing may be vehicle identification processing or the like.
