Infrared Image Enhancement Technology in the Processing of Anti-Counterfeiting
Some special coatings can allow specific ban infrared light through and absorb the visible light. Uses this feature, combining with infrared imaging to detect, judge and realize the purpose of anti-counterfeiting tamper-proof. But there are some defects existing in the gray con-verted images which extracted from infrared cameras, like noise, edge blur and so on. In order to improve the accuracy of the subsequent image processing, image enhancement processing is needed. In addition, infrared images collected from the rainy, snowy day and foggy weather also can appear fuzzy. The sharpen filter, uses differential calculation and processing, makes the edge information of image out-standing. Both human and machine can have a good recognition of it. Realizes anti-counterfeiting recognition and processing.
