What is patch image processing?
In patch-based methods, the image is divided into small patches and each patch is processed individually. The final output image is formed by reassembling the individually processed patches. There are many reasons for focusing on small patches rather than on the whole image.

Box filter, Gaussian filter and bilateral filters are kind of well-known filters used in image processing. As we know all these filters are used for de-blurring and smoothing.
