A color image processing method is provided. The color image processing method includes the step of: (a) indexing a color image by assigning representative colors of an image to a color space divided into a plurality of regions. The color image processing method may be applied to object-based image processing such as MPEG-7, and fast search and retrieval of multimedia content can be made.

A color image segmentation method is provided. The color image segmentation method includes the steps of: (a) calculating a first value representing the degree of difference between a pixel and the color of peripheral pixels based a plurality of pixel values of an input image; (b) obtaining a converted image by converting the first calculated value into a value of a predetermined scale; and (c) segmenting the converted image. According to the color image segmentation method, an effective and an automatic segmentation is possible, and a segmentation speed is high even when segmenting an image containing much noise.

A color image processing method and apparatus thereof are provided. The color image processing method includes the steps of (a) sorting image pixels according to the color distance between the image pixels and a central pixel, (b) grouping the sorted pixels into groups in which the difference in the intragroup color distance is minimum and the difference in the intergroup color difference is maximum, and (c) performing filtering by replacing a central pixel value with a predetermined pixel value determined by pixel values of pixels in the groups. The color image processing method can reduce the generation of edge blurring of the image in removing impulse noise from an image and filtering the same.

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.

A digital image segmentation method and device is provided. The method includes the steps of grouping an image stream into a plurality of continuous frame groups, setting one arbitrary frame as an I frame and the others as P frames in each group, segmenting the I frame into a plurality of regions, and segmenting the P frames by obtaining motion vectors, using motion prediction, of the segmented I frame regions, respectively, with respect to each of the P frames, by moving the segmented I frame regions by the respective motion vectors, and by setting the moved I frame regions as segmented P frame regions. Accordingly, the segmentation of the I frame is applied to the P frame segmentation, and a conventional segmentation process consuming excessive time with respect to all frames does not need to be performed. Thus, rapid segmentation can be performed.
