Current solutions to noise problems, one of the best methods, BM3D,
Three dimensional block (BM3D) algorithm:
It first divides the image into a certain size block, according to the similarity between the tiles, two-dimensional images of structures with similar blocks together to form a three dimensional array, then use federated filtering methods to deal with these three-dimensional array, and finally, by using the inverse transform, after processing the results back to the original image, to get the de-noised image. This method does work, it not only has a higher signal to noise ratio, and the Visual effect is very good.
