An image retrieval method based on fractal image coding

Fractal coding has been proved useful for image compression. It is also be proved effective for image retrieval based on content. We generate image index file utilize fractal image code, also define the distance between two images as the measure standard for matching similar image. Differently with image compression we don't pay more attention on image compression ratio, but more care about the costing time that used to searching the satisfied results. So we improved image partition method based on quadtree method, reduced the number of range blocks of image. The experimental results show the approach we proposed can obtain satisfied image retrieval results and has stability.
