Color image processing method and apparatus thereof
First Claim
1. A color image processing method for retrieving a color feature descriptor for describing color features of an image, the method comprising the steps of:
- (a) obtaining color vectors of an input image;
(b) classifying the color vectors to obtain dominant colors of the input image and the ratios thereof; and
(c) representing the dominant colors and the ratios thereof as a color feature descriptor of the input image.

Abstract
A color image processing method for retrieving a color feature descriptor for describing color features of an image is provided. The color image processing method includes the steps of (a) obtaining color vectors of an input image, (b) classifying the color vectors to obtain dominant colors of the input image and the ratios thereof, and (c) representing the dominant colors and the ratios thereof as a color feature descriptor of the input image. The color image processing method is applied to an object-based image processing method, thereby allowing fast search and retrieval of multi-media contents.
