利用MPI提供的库函数,提出了基于MPI的分形图像压缩并行化算法,将图像的定义域块和值域块的搜索匹配过程分配给多台处理器同时执行.实验结果表明,利用MPI来进行分形图像压缩,可以缩短压缩时间,在不改变压缩比的情况下,得到较好的加速比.
Uses MPI function and proposes a fractal image compression parallel algorithm based on MPI. Assign the search and match process of domain blocks and range blocks of the image to several processors for executing. The experiments show that this method can reduce the compression time of the image and achieve a high speedup while not reducing the compression rate.
