Color Exaggeration for Dichromats Using Weighted Edge
Dichromats recognize colors using two out of three cone cells; L, M, and S. To extend the ability of dichromats to recognize the color difference, we propose a method to expand the color difference when observ...

Interactive Shadow Removal from a Single Image Using Hierarchical Graph Cut
We propose a method for extracting a shadow matte from a single image. The removal of shadows from a single image is a difficult problem to solve unless additional information is available. We use user-supplie...
