Fig. 6From: Patch-based models and algorithms for image denoising: a comparative review between patch-based images denoising methods for additive noise reductionThe principal components “axis” of the house image: a is the input image, b is the first 16 principal axes of the all patches obtained from the house image, and c is the last 16 principal axes of the all patches obtained from the house image [13]Back to article page
