Embodiment Construction
[0040] In order to further understand the invention content, features and effects of the present invention, the following examples are given here, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0041] see figure 1 , a human privacy recognition and processing method based on X-ray backscattered images, comprising the following steps:
[0042] Step 1, image preprocessing; specifically:
[0043] S101, the original image is grayscaled; in this system, a bitmap (X-ray backscattered human body image) is obtained through the Bitmap class variable, and all pixels of the image are traversed, and we take 30% of red for the RGB value of each point , 59% of green, and 11% of blue, and add their values together to obtain the gray value corresponding to each pixel of the image, and realize the gray scale of the image;
[0044] S102. Perform binarization processing on the grayscale image obtained in step S101; the binarization of the image is to...

The invention discloses a human privacy recognition and processing method based on X-ray backscattered images, comprising the following steps: Step 1, image preprocessing; specifically, S101, grayscale processing; S102, image binarization processing; 2. Identification of private parts; specifically, S201, find the starting point on the inside of the two legs; S202, find the vertex of the angle; S203, offset the coordinate position of the vertex of the angle; step 3, blur the private parts, and The coordinate positions of the above-mentioned left starting point of the target, the right starting point of the target, and the vertex of the target angle determine the blurred triangle area, and then perform blurring processing on the pixels of the above-mentioned triangle area. The invention aims at quickly and accurately identifying and processing the private parts of the X-ray backscattered human body image, and realizes the protection of the privacy and security of the human body. The method has the characteristics of high execution efficiency, fast processing speed and high recognition accuracy.
Description
technical field [0001] The invention relates to the technical field of computer image processing, in particular to a human body privacy recognition and processing method based on X-ray backscattered images. Background technique [0002] With the advancement of science and technology and the increasing attention of people to public safety, various security inspection technologies, especially X-ray backscatter imaging technology, have been widely used in the field of security inspection to detect suspected dangerous goods carried by people. . Since X-ray backscatter imaging technology can penetrate people's clothing to scan the human body in all directions, it brings about the problem of human privacy and security. Therefore, the processing of private parts of X-ray backscattered human body images has become a necessary function of security inspection software. It is designed to automatically identify private parts from X-ray backscattered human body images and perform neces...
