摘要：
In this paper, we present a, classification algorithm in fractal image coding. Based on the contraction characteristics of. transformations in fractal image coding, the algorithm uses the notion of feature difference to speed up. the domain-range matching routine of the coding. The algorithm can effectively exclude pseudo matches during the process of domain-range matching and result in significant improvement of the rate-distortion performance. It can also be easily realized in cooperation with many other speedup schemes.
