Title: Color quantization of color images in a homogeneous color space
Abstract: Color quantization is to classify the colors of an image to a few classes of colors according to the visual effect of human eyes. So these few colors can be used to creat a new image and keep the color quantization errors between the new image and the onginal one to be the least.This paper gives the quantization of a color image in a horrogeneous color space of L *a *b *, which is transformed from a nonhomageneous color spece of RGB. Therefore the problem of nonhomogeneous chromatisom to human eyes can be solved. Firstly,, the data of a color image were saved into a single chain list. Then the list was scanned, finding two nodes whose chromatism is the least. Finally,the two nodes were combined into a new node. After sufficient dynamic calculation we got the palette of the color image quantized. The experimental results show that minishing the color quantization errors and improving its veracity are the catholicity and uniqueness of this method.Key words:
