Abstract:Wavelet transform has good local characteristics and multi-scale characteristic, it can multi-scale edge approximation, this makes it wide range of applications in image singularity detection and feature extraction. In this paper color edge extracted by using dyadic wavelet transform modulus maxima,and then using annular color histogram express image color features, using wavelet modulus maxima annular histogram express shape feature. Finally, the similarity between color images is computed by using a combined feature index based on the above two histogram. experimental results show that the approach has a good retrieval performance, and strong robustness to the image illumination change and geometry change.
