Image shadow detection method and system, and image segmentation device and readable storage medium

Abstract

Disclosed is an image shadow detection method, a system, an image segmentation device, and a readable storage medium. The method comprises the following steps: acquiring a chrominance component of an image; segmenting the image by a first segmentation rule based on the chrominance components of the image and the preset chrominance interval and acquiring a first segmentation result, the first segmentation result comparing a first region and a second region; calculating feature values of the first region or the second region in the image; carrying out the comparison processing to judge whether the image has shadow based on the feature value and the preset threshold value. According to the present disclosure, the image is segmented by the first segmentation rule and the first segmentation result is acquired. The first segmentation result is acquired based on the chrominance component and is not affected by shadows. The shadow area is identified by combining the first segmentation result with the judgment of feature values, thus reducing the possibility of shadow misjudgment.
