Roughness compensation method and system, image processing device, and readable storage medium

Abstract

Disclosed are a roughness compensation method and system, an image processing device, and a readable storage medium. The roughness compensation method includes the following steps: acquiring a roughness value of a target region in an image and position information of pixels in the target region; averaging the position information of the pixels in the target region to obtain average position information; determining whether the average position information is located in a preset compensation region; and compensating and updating the roughness value when the average position information is located in the preset compensation region; or skipping compensating the roughness value when the average position information is not located in the preset compensation region. In the present disclosure, a determination result of whether the average position information is located in a preset compensation region is used as a basis of compensation, and a compensated roughness value is used for an image processing program such as shadow recognition, which can effectively reduce erroneous determination of shadow recognition results.
