在超级计算机上进行图像处理的并行小波算法(英文)

Using Parallel Wavelet Trans form Algorithm to Image Processing on Super computer

分析了小波变换的并行特征，给出了一种并行小波变换算法，使用该算法在超级计算机ＣｒａｙⅠ和ＣｒａｙⅡ上进行了图像（５１２５１２）边界检测，对所得结果进行了比较。

In this paper we describe the parallel properties of wavelet transform.A parallel wavelet transform algorithm is given.We use this algorithm to process a 512*512 image edge detection on srpercomputer Cray\|Ⅰand Cray\|Ⅱ.In the end,the results are compared,which show that the way above can greatly improve the speed\|up ratio.
