Salt and Pepper Noise Removal with Noise Detection and a Patch-Based Sparse Representation
Images may be corrupted by salt and pepper impulse noise due to noisy sensors or channel transmission errors. A denoising method by detecting noise candidates and enforcing image sparsity with a patch-based sparse representation is proposed. First, noise candidates are detected and an initial guide...
