Dichromats recognize colors using two out of three cone cells; L, M, and
S. For example, red-green color blinds cannot distinguish the color between
red, yellow, and green. To extend the ability of dichromats to recognize
the color difference, we propose a method to expand the color difference
when observed by dichromats. We analyze the color between the neighboring
pixels in chromaticity space. In addition, we employ multiresolution analysis
to form the Poisson equation. Our multiresolution analysis is non-linear
depending on the saturation of each pixel’s color. Solving the multiresolution
Poisson equation results in the color enhanced image. |
