The invention provides an image motion blur removal method and device. The method includes: inputting the original image to be processed; performing edge detection on the original image in the direction of motion to extract edge information in the first direction of the moving target in the original image; performing edge detection perpendicular to the direction of motion on the original image to extract the original image The edge information of the moving target in the second direction perpendicular to the direction of motion; obtain the moving target area in the original image according to the edge information of the first direction and the edge information of the second direction; perform de-motion blur processing on the moving target area; The moving target area is merged with the non-moving target area in the original image to generate and output the overall image after motion blurring. The image motion blur removal method provided by the present invention only processes the moving target area without additional hardware support, and further simplifies the amount of calculation and reduces noise interference on the premise of ensuring the quality of target restoration.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of digital image processing, and in particular, to an image motion blur removal method and device. Background technique [0002] Video surveillance is widely used in the fields of public security and traffic management. Target recognition and other processing based on video images can greatly improve security early warning and analysis and processing capabilities. However, due to various physical defects of imaging devices in the existing video surveillance system, or the use environment is not conducive to good imaging, and user's operation problems, etc., it is easy to have motion blur when imaging fast moving objects, resulting in the details of the captured images. It is not clear enough, which is not conducive to the user's subsequent processing and analysis. [0003] Existing video image de-blurring methods such as Chinese patent (application number: 201110209524.8) use a two-sta...
