Abstract: This paper presents a new scheme to speed up fractal image compression based on HV partition. In this scheme, we propose a new approach based on character track that can speed up the process of searching appropriate domain blocks. In this technique we first abstract the range block's characters, then when we searching in the domain block pool, only domain blocks which characters are exactly fit with the range block could transact the process of matching. The experimental result shows that with this technique we can improve the speed of encoding more one hundred times than the original algorithm. !22
