경계 강조를 이용한 수정된 MSRCR 알고리즘을 이용한 역광사진

초록

Retinex Algorithm is one of the most outstanding algorithms to enhance back-litght images in image processing. In this paper, we propose a image enhancement algorithm which is based on MSRCR (multi-scale retinex with color restoration) algorithm. It uses the Canny edge detection to emphasize the edge and thus the color restoration process is also affected. As a result, this algorithm can recover edge at bright part of image and enhance contrast.
