Abstract
It is found that application of Retinex color constancy algorithm in machine vision can weaken light interference on printing chromatic aberration. We propose a new method of fusion of Weighted Least Squares and Multi-Scale Retinex in the L*a*b* color space for the purpose of further enhancing the degree of recovery of prints colors. The effectiveness of the proposed method is tested against experiments on images of the same original print acquired in different illuminants. The method exhibits a good application prospect in machine vision in virtue of its great color consistency capability in maintaining the color of the original print.
