Effective speckle noise suppression in optical coherence tomography images using nonlocal means denoising filter with double Gaussian anisotropic kernels
Non-local means (NLM) filter is one of the state-of-the-art denoising filters. It exploits the
presence of similar features in an image and averages those similar features to remove …
