在信号恢复尤其是图象恢复领域，需要大量快速运算算法．文内对一系列用中值迭代滤波器恢复高斯噪声信号的问题了进行了讨论，并提出了其滤波器在分布式多数据流、多指令流计算机的并行算法，着重讨论了Ｐ递归滤波器的并行高效实现算法，还提出了在去噪、图象细节保护和去除边缘效应方面有较好性能以及并行计算实现方面有较高效率的混合式中值并行滤波器 In the area of ​​signal recovery, especially in image restoration, a large number of fast arithmetic algorithms are required. In this paper, a series of problems of using Gaussian noise signal to recover the Gaussian noise signal are discussed. A parallel algorithm of the filter in distributed multi-stream and multi-instruction flow computer is put forward. The P recursive filter Parallel parallel algorithm for efficient implementation, a hybrid median-parallel filter that has better performance in denoising, image detail protection and edge removal, and higher efficiency in parallel computing is also proposed
