Abstract

This work presents an efficient and automatic image-recoloring technique for dichromats that highlights important visual details that would otherwise be unnoticed by these individuals. A paired-comparison evaluation was performed with color vision deficient volunteers and its results indicate that the proposed technique produces superior results when compared to previous automatic recoloring techniques. Another contribution of this work is an efficient contrast-enhancement algorithm for color-to-grayscale image conversion that uses both luminance and chrominance information. It also introduces an error metric for evaluating the quality of color-to-grayscale transformations.
