In image processing, there are many algorithms because their inherent complexity is a natural time-consuming large, and the data volume contained in the image itself is larger than the average object. Therefore, for such algorithms, the speed of execution depends largely on the Performance of hardware. Currently, popular CPUs are at least two cores, a little better than four or even eight cores. Therefore, if we can make full use of these resources, w
