| Abstract: | A new algorithm of retrieval for texture images in DCT compressed domain is presented. The statistical features of the texture images is computed directly from DCT coefficients, and used for image retrieval. Theoretical analysis and experimental results show that the approach achieves good performances in terms of retrieval accuracy and effectiveness. It is also invariant to rotation. |
