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 body private part recognition and processing method based on X-ray back scattering images. The method includes the following steps of firstly, conducting image preprocessing which particularly includes graying processing and image binaryzation processing, secondly, recognizing a private part, and thirdly, conducting fuzzification processing on the private part, wherein in the second step, particularly, initial points of the inner sides of the two legs are found; the peak of the included angle is found; the coordinate position of the peak of the included angle is shifted; in the third step, a triangular region to be fuzzed is determined according to the coordinate position of a target left starting point, the coordinate position of a target right starting point and the coordinate position of the peak of the included angle of a target, and then pixels of the triangular region are fuzzed. The method aims to quickly and accurately recognize and process the X-ray back scattering human image private part, and human body private part safety protection is achieved. The method has the advantages of being high in execution efficiency, processing speed and 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...
