A color image retrieval method based on color moment and color variance of adjacent pixels
This paper first introduces three simple and effective image features - the color moment (CM), the color variance of adjacent pixels (CVAP) and CM-CVAP. The CM feature delineates the color-spatial information of images, and the CVAP feature describes the color variance of pixels in an image. However, these two features can only characterize the content of images in different ways. This paper hence provides another feature CM-CVAP, which combines both, to raise the quality of similarity measure. The experimental results show that the image retrieval method based on the CM-CVAP feature gives quite an impressive performance.
