Image Retrieval Method Based on Hybrid Fractal-Wavelet Image Coding

摘要

This paper presents a hybrid image coding method combined with fractal image coding and wavelet transform. Exploite wavelet transform decomposed an image into some different frequency subbands. We introduced two different processing courses of fractal coding in high frequency subbands and low frequency subbands, obtained corresponding coefficients as index file of an image. Differently with image compression we pay more attention on the accuracy of image retrieval and time consuming. From experimental results we can obtained satisfied results of image matching exploited index file which produced by our proposed hybrid image coding method.
