A discriminative color quantization depending on the degree of focus

초록

In this paper, we propose a discriminative color quantization algorithm depending on the degree of focus of the regions. When we take pictures, we usually focus the object that we want to emphasize. This means that focused area on the photograph contains important information. If the focused area is displayed with more colors, we can express the important information in more detail. This paper proposes a color quantization method that determines the focused area and assigns more colors for the area. © Springer-Verlag Berlin Heidelberg 2007.
