The preset corresponding relationship between the attention object and the receiving end may also be a corresponding relationship between the attention object and the authority level of the receiving end. Specifically, each level of authority level corresponds to a plurality of administrators, the higher the security level of the attention object is, the higher the security level of the attention object may correspond to only the higher high authority level, and the lower the security level of the attention object may correspond to most of the authority levels.

Fig. 2 is a flowchart of another image processing method according to an embodiment of the present invention, and as shown in fig. 2, according to another aspect of the embodiment of the present invention, there is also provided another image processing method including the steps of:
step S202, receiving a transmission image sent by an image acquisition end;
step S204, according to the user authority, shielding the image elements whose authority is prohibited from receiving in the transmission image;
and step S206, transmitting the transmission image after the shielding processing to a display device for displaying.
Through the steps, the transmission image sent by the image acquisition end is received; according to the user authority, carrying out shielding processing on the image elements which are forbidden to be received by the authority in the transmission image; the method for transmitting the transmission image after the shielding processing to the display device for displaying is characterized in that the receiving end authority corresponds to the image element which is forbidden to be received, and the shielding processing is carried out, so that the aims of shielding the partial image element of the image according to the receiving end authority and selectively displaying the image are fulfilled, the technical effects of improving the security and confidentiality of image transmission are achieved, and the technical problems of different confidentiality levels and lower security of a graph transmission system caused by different monitoring objects in the related technology are solved.
The main body of the above steps may be the image receiving end.
Optionally, the shielding, according to the user right, the image element whose right is prohibited from being received in the transmission image includes: determining image elements in the transmission image, wherein the image elements comprise at least one of an object region, a text region and a background region in the image; determining image elements which can be received by the user authority and image elements which are forbidden to be received by the user authority according to the user authority; and shielding the image elements which are forbidden to be received and correspond to the user authority.
It should be noted that this embodiment also provides an alternative implementation, which is described in detail below.
In this embodiment, a corresponding relationship between the attention object and an administrator may be set at the acquisition end in advance, and the administrator may be a user of the image receiving end and may log in the image receiving end through an account. For the image acquired by the same image source device, an administrator with higher authority can see a complete image through the receiving end, an administrator with lower authority cannot see an attention object with higher security level in the image through the receiving end, and specifically, the acquisition end shields the attention object with higher security level in the image according to the preset corresponding relationship between the attention object and the administrator and then transmits the attention object to the receiving end used by the administrator with lower authority.
Therefore, the attention object in the image acquired by the image source device can be selectively shown to the administrators with different authorities. Even for the image collected by the same image source device, the attention objects seen from the image by management sources with different authorities are different. The monitoring safety of the graph transmission system can be improved.
Fig. 3 is a schematic diagram of an image processing system according to an embodiment of the present invention, as shown in fig. 3, the image processing system including: the image source device, the acquisition end, the receiving end and the display device. The image source device may be a camera or a computer, and is usually a camera in a monitoring scene.
The acquisition end is connected with image source equipment. The acquisition end comprises an S1 module, a processing module and an S2 module. The S1 module is used to capture images in an image source device. The processing module is used for identifying the concerned object from the image and shielding the acquired image according to the preset corresponding relation between the concerned object and the administrator. The module of S2 is used to code the image processed by the processing module.
The receiving end is connected with the display device. The receiving end comprises an R module, and the R module is used for decoding the received coded data and displaying the decoded and restored image on the display equipment.
The processing flow of the present embodiment is specifically as follows:
In this step, the S1 modules of the multiple capturing terminals capture images captured by the image source device, and send the captured image data to the processing modules of the respective capturing terminals. One image source device corresponds to at least one acquisition end.
As shown in fig. 3, S11 in the capturing end 1, S12 in the capturing end 2, and S13 in the capturing end 3 capture images of the image source device, respectively, and it can be understood that the images captured by the three S1 are identical.
Step 2, the S1 module sends the collected image to a processing module; the processing module identifies preset attention objects from the received images.
It should be noted that, since the object of interest is fixed in most monitoring scenarios or fixed for a period of time, even if the transmission changes, the change amplitude is not too large. Therefore, the image of each object of interest can be preset in the processing module, so that the processing module can accurately recognize each object of interest from the image. For example, the object of interest includes a building, a vehicle, a specific area, an image of the building, an image of the vehicle, and an image of the specific area may be preset in the processing module.
In this step, the processing module identifies each object of interest from the image data sent from the S1 module based on a preset image of the object of interest.
And 3, determining the concerned objects which are not watched by the administrator by the processing module according to the preset corresponding relation between the concerned objects and the administrator, and recording as the target concerned objects.
It should be noted that the processing module is preset with images of the objects of interest and the corresponding relationship between the objects of interest and the administrator. The object of interest has a correspondence with an administrator, that is, the administrator has the right to see the object of interest in the image.
For example, the objects of interest include ship 1, ship 2, building 1, and building 2, where ship 1 corresponds to administrator 1 and administrator 2, ship 2 corresponds to management source 1 and administrator 3, building 1 corresponds to administrator 1 and administrator 4, and building 2 corresponds to administrator 1 and administrator 5.
In this step, the processing module sequentially judges whether each identified attention object has a preset corresponding relationship with the administrator according to the preset corresponding relationship between the attention object and the administrator; if all the concerned objects have a preset corresponding relation with the administrator; and skipping the step, and if at least one concerned object does not have a preset corresponding relationship with the administrator, marking the at least one concerned object as a target concerned object.
For example, as shown in fig. 3, the attention objects include a white boat corresponding to the administrator 1 and the administrator 3 and a black boat corresponding to the administrator 2 and the administrator 3; administrator 1 uses receiving end 1, administrator 2 uses receiving end 2, and administrator 3 uses receiving end 3; then, the target object of interest is a black ship for the administrator 1, a white ship for the administrator 2, and no target object of interest for the administrator 3.
Optionally, the preset corresponding relationship between the attention object and the administrator may also be a corresponding relationship between the attention object and the administrator permission level.
Specifically, each level of authority level corresponds to a plurality of administrators, the higher the security level of the attention object is, the higher the security level of the attention object may correspond to only the higher high authority level, and the lower the security level of the attention object may correspond to most of the authority levels.
Table 1 is a correspondence table of the attention object and the administrator authority level, as shown in table 1. In table 1, the ship 1 has a higher security level and corresponds to the first-level authority with the highest authority level; the security level of the ship 2 is medium and corresponds to 2 higher authority levels, namely a first level and a second level; the security level of building 1 is low and corresponds to all three levels of authority.
TABLE 1 correspondence table of attention objects and administrator permission levels
| Object of interest | Administrator |
| Ship | |
| 1 | First level of authority |
| Ship 2 | A first level of authority; two level of authority |
| Building 1 | A first level of authority; secondary authority; three level of authority |
Further, the attention object may be divided according to the security level, and the preset corresponding relationship between the attention object and the administrator may also be the corresponding relationship between the security level of the attention object and the authority level of the administrator, as shown in table 2.
Table 2 is a table of correspondence between the security level of the object of interest and the administrator authority level, as shown in table 2. In table 2, the first-level security level with the highest security level corresponds to the first-level authority with the highest authority level; the second-level security level with medium security level corresponds to higher 2 authority levels, namely, the first level and the second level; the three levels of security with the lower security level correspond to all three levels of authority. Of course, the privacy level corresponding to each object of interest needs to be set in advance.
TABLE 2 Table of correspondence between security level of object of interest and administrator privilege level
| Privacy level of an object of interest | Administrator privilege level |
| First level of security | First level of authority |
| Second level of security | A first level of authority; two level of authority |
| Third level of security | A first level of authority; secondary authority; three level of authority |
Step 4, the processing module determines the image information of the target attention object in the received whole image, wherein the image information comprises the position and the range of the image of the target attention object in the whole image; the processing module sends the received entire image and the image information of the target object of interest to the S2 module.
Specifically, the position may be a coordinate value of a pixel at the upper left corner of the image of the target attention object, and the range may be the length and width dimensions of the image of the target attention object.
Step 5, the module of S2 carries on the macroblock to the whole picture received and divides; according to the image information of the target attention object, marking the macro block where the image of the target attention object is located in the whole image as the target macro block.
In this step, the S2 module first performs macroblock partition on the received whole image; and marking the macro block where the image of the target attention object is located in the whole image as a target macro block according to the received image information of the target attention object.
Fig. 4 is a schematic diagram of image macroblock processing according to an embodiment of the present invention, as shown in fig. 4, a small square in the diagram is a schematic diagram of macroblock division, a white boat is a target object of interest, and a macroblock marked as 1 in the diagram is a target macroblock.
In practice, the macro block is usually 16 × 16 pixels, and is smaller than the small square in fig. 4, and fig. 4 is only a schematic diagram.
Step 6, the module of S2 encodes the whole image, replaces the target macro block with the preset replacing macro block, generates the encoded data; and the acquisition end sends the encoded data to the receiving end.
The preset replacing macro block can be a pure color map of the macro block size.
In this step, the S2 module firstly determines whether a macroblock is marked (target macroblock) in the encoding of the whole image, if so, discards the target macroblock and replaces it with a preset replacement macroblock, and if not, then encodes normally; and the acquisition end sends the generated coded data to the receiving end.
It is understood that the generated encoded data has the image of the target object of interest replaced by the preset replacement macro block.
Step 7, R1 in the receiving end decodes the received coded data to obtain image data; the image data is displayed in a display device.
As an example based on fig. 4, the target macroblock in fig. 4 is replaced by a preset replacement macroblock, the image data after replacement is encoded to generate encoded data, and R1 decodes the encoded data to obtain an image, and fig. 5 is a schematic diagram of the image target macroblock after processing according to the embodiment of the present invention, as shown in fig. 5. It can be seen that the white boat in fig. 5 has been completely shielded and cannot be seen by the administrator through the receiving end, achieving the desired effect.
For another example, as shown in fig. 3, for the administrator 1, the target object of interest is a black ship, and therefore, the administrator 1 cannot see the black ship at the receiving end 1; for the administrator 2, the target object of interest is a white boat, and therefore, the administrator 2 cannot see the white boat at the receiving end 2; there is no target object of interest for the administrator 3, and therefore the administrator 3 is able to see the complete image at the receiving end 3.

By the device, the image to be transmitted is collected; according to the authority of the image receiving end, shielding the image elements which are forbidden to be received by the authority in the image to be transmitted; the image to be transmitted after the shielding processing is sent to the image receiving end, the shielding processing is carried out through the image elements which correspond to the receiving end authority and are forbidden to be received, the purpose of shielding processing partial image elements of the image according to the receiving end authority and selectively transmitting the image is achieved, the technical effects of improving the safety and the confidentiality of image transmission are achieved, and the technical problems that the confidentiality grade is different and the safety of a graph transmission system is lower due to the fact that monitoring objects are different in the related technology are solved.
