摘要： 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.

摘要： Digital image coding/decoding apparatus using watermarking, and methods thereof are provided. The digital image coding apparatus includes a discrete wavelet transform portion for performing discrete wavelet transform on a host image to be transmitted thereon, thereby outputting M×M discrete wavelet coefficients where M is a predetermined positive integer, a significant coefficient extraction portion for extracting a predetermined percentile of upper significant coefficients among M×M wavelet coefficients, a pseudo-random number generator for generating pseudo-random numbers in accordance with a predetermined rule corresponding to an encryption code, and a coefficient replacement/combination portion for obtaining replacing location data representing the N×N replacing locations, where N is a predetermined positive integer smaller than M, replacing and combining coefficients corresponding to N×N replacing locations selected among M×M wavelet coefficients with N×N significant wavelet coefficients. Since a distorted host image transmitted from a severely noisy environment is corrected using the current image, the flow of information is continuous. Also, even when the image is abruptly changed, an error in correcting the image is not generated.

摘要： 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.
