This paper integrates the advantages of the traditional co-occurrence matrix and generalized image co-occurrence matrix and proposes an improved method based on generalized image co-occurrence matrix. The new approach constructs four co-occurrence matrixes based on generalized image in four directions, and then it picks up the texture parameters of the four co-occurrence matrixes for image retrieval. The experimental results show that the new method has an advanced general performance and the retrieval efficiency is improved greatly when the image gets a rotation and great change in size.
