| Zusammenfassung: | The invention relates to the technical field of image processing, in particular to an image enhancement method based on computer vision, and the method comprises the steps: obtaining an outdoor monitoring grayscale image and dynamic object local regions in the image, and obtaining the enhancement expectation of each dynamic object local region and the overall enhancement demand of the outdoor monitoring grayscale image, and according to the enhancement expectation of the dynamic object local area and the overall enhancement demand of the outdoor monitoring grayscale image, obtaining an adaptive enhancement coefficient of each dynamic object local area in the outdoor monitoring grayscale image, and according to the adaptive enhancement coefficient of the dynamic object local area and the grayscale value of the pixel point in the area, obtaining an outdoor monitoring enhanced image. According to the method, the mapping values of the gray values of all the pixel points in the local area of each dynamic object ar |
