Outline of Final Research Achievements

This research is to develop image processing techniques by which color defectives can recognize color differences that they cannot natively sense. Such techniques often change original colors themselves to distinguishable ones. However, we took a different approach, and use image attributes other than color, such as textures. We developed method using dots and lattices as the texture. This method has been proved effective for figures or graphs in documents. We also developed a method using image bricking, which is effective for display of computers or smart phones.
