An Improved Multiresolution Fractal Decoder
-
摘要: 为了减小分形解码方法的计算复杂性,基于对一种分形编码方法所使用PIFS (Partitioned Iterated Fuction System)不动点多分辨特性的研究,提出一种改进的多分辨分形 解码方法,与Oien和Lepsoy的塔式方法相比,需要更少的计算量.实验结果验证了有关结论的 正确性.Abstract: Based on the multiresolution properties of PIFS (Partitioned Iterated Function System)'s fixed point used in the Oien and Lepsoy's fractal encoder, an improved multiresolution fractal decoder is proposed in this paper. Compared with the Oien and Lepsoy's pyramidal fractal decoder, the proposed decoder can further reduce computation complexity. Related conclusions are verified with experimental results.
