A shadow removal from an image based on the region segmentation by using the probabilistic relaxation method

Abstract

In this paper, we propose a new method to remove shadows from a real image. In this method, the image is divided into shadow areas and sunshine areas by using the probabilistic relaxation method. The level of color and brightness in the shadow area are adjusted to those of the sunshine area, respectively. The adjustment rate is modified according to the distance from the boundary. The effectiveness of the proposed method is verified by applying it to images containing a shadow area.
