Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
A color image processing method for retrieving a color feature descriptor for describing color features of an image, the method comprising: segmenting an input image into a plurality of regions; obtaining color vectors of each of the plurality of regions; obtaining at least one class of the color vectors by classifying the color vectors of each of the plurality of regions based on a distribution of values of the color vectors; obtaining at least one dominant color and ratio thereof from the at least one class; and representing a color feature descriptor of the input image using the at least one dominant color and ratio thereof.
Claim 2
Dependent Claim
106 words
A color image processing method for retrieving a color feature descriptor for describing color features of an image, the method comprising: segmenting an input image into a plurality of regions; obtaining color vectors of each of the plurality of regions; obtaining at least one class of the color vectors by classifying the color vectors of each of the plurality of regions based on a distribution of values of the color vectors; obtaining at least one dominant color and ratio thereof from the at least one class; and representing a color feature descriptor of the input image using the at least one dominant color and ratio thereof.
Claim 3
Dependent Claim
97 words
A color image processing method for retrieving a color feature descriptor for describing color features of an image, the method comprising: segmenting an input image into a plurality of regions; obtaining color vectors of each of the plurality of regions; classifying the color vectors of each of the plurality of regions to obtain at least one class of the color vectors; obtaining at least one dominant color and ratio thereof, from the at least one class; and determining the at least one dominant color and the ratio thereof as a color feature descriptor of the input image.
Claim 4
