Content-based color image retrieval system using color difference features
In this paper, we propose a new color image retrieval scheme based\non color features. The goal of this scheme is to effectively retrieve\nimages similar to a query image in a color image database. In this\nscheme, a color image is first divided into three planes. Then the\nlocal features of the given image can be found by calculating the\ncolor difference of each plane. Thereafter, the color difference\nco-occurrence matrix (CDCOM) of each color image can be derived through\nthese local features. The CDCOM is regarded as the global feature\nof the color image. Consequently, CDCOM is used to find images similar\nto the query image. Experiment results show that the proposed scheme\ncan effectively retrieve the desired and similar images. © 2008\nIEEE.
