Abstract

The automatic color feature extraction is one of the most important issues in a variety of research fields，such as image recognition，image analysis，color harmony，and so on．In this paper，we propose a method to extract a few dominant colors from images by using basic color categories，which are known as perceptual color categories of human．For that，we first extracted a number of dominant color candidates by image clustering．Next，we removed candidate colors which have low saturation or form small area in the image space．Finally，we merged perceptually similar candidate colors using the basic color categories．In this way，we can get the final dominant colors．We have compared our results with those of previous methods，and confirmed the validity of our method．
