Retrieve Images Based On Regional Characteristics And To Achieve

In this paper, we manipulate the image before distill the eigenvalue; compare the effects when existing color models are used in image retrieval. Analyze the methods of depict and distill the shape and figure. And based on these theories and methods, an image retrieval by region units is presented. First, when scan image orderly, continuously incorporate neighbor similar pixels in color and get several region units. Then, write the values of color, shape, and position into database. Last, when searching, user can determine the weights of three properties before scan the database of images. Computer verifies its effect, and experiment results are exact and comprehensive. Based on the characteristic of image data, a quick index technology of large numbers of data is presented. It classifies and assembles the similar images by particular arithmetic, so reduce the range when searching, therefore you can find the object images quickly and exactly. Analyze the specialties of LAN and WAN, present the respective system frame and retrieval mode.
