The Research Of Methods For Color Image Retrieval

Along with the arrival of multimedia time, people can get more and more image information. How to provide an efficient approach to query these images which have rich content therefore becomes an active hot point in the area of retrieval research. Content based image retrieval (CBIR) is just one of key technologies for such a problem.Abstracting image's content in the level of feature is the base of CBIR. Its main idea is: Analyzing visual images collected from the bottom features (such as color, shape, texture, space relations, etc.) to measure the similar extent between the images to achieve CBIR. In the bottom of the visual identity, the technology in feature extraction uses computer vision technology and digital image processing techniques, and use of digital images major similarities matching technology. This paper is mainly targeted at the color image retrieval technology research as the following points :First: Using color histogram in RGB color space to retrieve the image...
