Improved Multi-Scale Retinex Approaches for Color Image Enhancement

Abstract

In this paper, an improved multi-scale Retinex with color restoration is proposed by correcting some distortion on color rendition. By using the proposed method, results of image enhancement are obtained and compared further with those acquired by employing the single-scale Retinex, the multi-scale Retinex and the conventional multi-scale Retinex with color restoration. For HSV space shows better color channel independence by comparison with RGB space, a multi-scale Retinex in HSV space is given out and explored to enhance images. The experimental results do show distinct information and effects.
