Based On Visual Characteristics Of The Color Image Edge Detection And Segmentation Techniques Study

Color is one of the important characteristics of color image. Because of rapiddevelopment of multimedia technology, it needs computer to process lots of color image, ofwhich is related to processing color a lot. So how to process color image from colorcharacteristics has become one important subject of color processing research. Color lmageedge detection and color image segmelltation techniques are important contents of patternrecognition and bases of computer real time control in many fields.This paper rests from visual character, discusses the way of transformation betweenRGB Color Space (industry color model, color space of color image showed in CRT) andHSI Color Space (visual color model, its design reflects the way humans see color), andestablishes transformation formula, which makes it more convenient and efficient to processcolor. On the bases of this, the paper discusses the way of color image edge detection withcolor vision characteristic, compares the results of edge detection in several color formatswidely used and modifies the color format used in literature [25], then brings forward anefficient way of edge detection. Not only the edges in brightness but also edges in hue isdetected in this way. At the same time, the segmentaion of color image in the color visionsystem with the recognition principle of distance nearest is also studied and the result ispreferable satisfactory. In the end, this paper discusses the applications of color image edgedetection and segmentaion theories in printing controlling preliminarily.
