A digital camouflage generation algorithm using color similarity

Abstract

A novel digital camouflage generation scheme based on color quantization is proposed. First, a color similarity measurement in RGB color space is presented by exploiting the similarity of two color vectors. Then main colors in the background of the host image are extracted by combining color similarity and color quantization. Finally, the camouflage image is generated by replacing target pixels with main background colors. Simulated experiments prove that the proposed algorithm can achieve full fusion of the target and the background, and the generated camouflage image has satisfactory visual quality.
