notes ： The meaning here should be that when a pixel is aggregated, there is no way to aggregate all the global pixels through only one iteration , Because some pixels will be missed in eight directions . But if we do another aggregation based on the first iteration , Basically, all global pixels can be aggregated when aggregating this pixel . That is, nonlocal method .
The difference between nonlocal method and global method ： Nonlocal method is to link all pixels in the whole image for aggregation , But the global method is to build an energy function for the whole image , Find the minimum and extreme value .
