Problems solved by technology

[0004] The reduction of X-ray inspection dose will inevitably lead to a decrease in the clarity and contrast of the image formed by the radiation, making it difficult to identify the detailed information in the image, which will directly affect the effect of image recognition and the efficiency of security inspection work, and even bring major safety hazards

Abstract

The invention discloses an image reinforcing method for a security inspection system. The method comprises the steps of: (A) rebuilding and displaying an initial radiation image on a basis of initial data obtained from a detector of the security inspection system; (B) selecting a target area in the displayed initial radiation image; and (C) enhancing the contrast ratio of the selected target area and displaying the enhanced image. With use of the method for partially enhancing the radiation image disclosed by the invention, an operator can partially enhance the contrast ratio of a suspicious area conveniently to highlight the detailed information of an interesting area, so that display effect of the image can be improved.

Description

technical field [0001] The invention relates to image processing technology in the field of radiation imaging, in particular to a method for enhancing radiation images in a human body safety inspection system. More specifically, it relates to an image processing method that realizes partial enhancement of the radiation image by operating suspicious regions in the radiation image. Background technique [0002] The human body safety inspection system is a safety inspection system that uses radiation sources, such as X-rays, to irradiate the human body to determine whether there are dangerous goods, drugs, and contraband inside and outside the human body. Because it can check the surface and inside of the human body at the same time, it can effectively highlight the display of explosives, drugs and other contraband. The image is intuitive and easy for operators to judge and identify. It is widely used in airports, customs, prisons, special mines, and border inspections Station...
