James–Stein Type Center Pixel Weights for Non-Local Means Image Denoising
James–Stein Type Center Pixel Weights for Non-Local Means Image Denoising
Non-Local Means (NLM) and variants have been proven to be effective and robust in many image denoising tasks. In this letter, we study the parameter selection problem of center pixel weights (CPW) in NLM. Our key contributions are: 1) we give a novel formulation of the CPW problem from the …
