Color stereopsis is a phenomenon in the human visual system (HVS) in which a long wavelength color is perceived as being located closer than a short wavelength color. Although many psychophysical studies on color stereopsis have been carried out, its practical application is not fully investigated. In this letter, we propose a new image enhancement algorithm using color stereopsis between red and blue colors. First, the relationship of red and blue colors to the depth perception is analyzed. Then, a simple but practical image enhancement algorithm is presented based on the analysis result. The experimental results demonstrate the effectiveness of the proposed algorithm.
