Fast fractal coding based on detail information classification and structure similarity
基于细节信息分类和结构相似的快速分形编码方法

The conventional fractal coding scheme suffers from long encoding time.A new fractal coding method was proposed based on detail information classification(DIC) and structure similarity(SSIM) index.DIC was implemented based on distribution of detail information which was discrepancy between pixel and its adjacent pixels.SSIM index measured the similarity between range block and domain block from luminance,contrast and structure.The combination of DIC and SSIM index can accelerate the classification and reduce time of matching computation.Experiment results on test images show that the presented method can decrease the coding time whilst maintain decoding quality.
