Claim Text:
1. A method for removing noise from an image, the method comprising: selecting one or more patches of a first image having a noise profile as a set of noisy patches, each noisy patch having a set of n by n pixels; selecting one or more patches of a second image without the noise profile as a set of clean patches, each clean patch having a set of n by n pixels; estimating one or more patch types for the set of noisy patches; constructing a shrinkage function model based on the one or more patch types and the set of n by n pixels of the noisy patch and the clean patch respectively; applying the shrinkage function model to a third image to obtain a set of n by n denoised patches; and reconstructing the set of n by n denoised patches to remove noise from the third image.
