This paper proposes a two-stage method for hand depth image denoising and superresolution. using bilateral filters and learned dictionaries via noise-aware orthogonal matching pursuit (NAOMP) based K-SVD. The bilateral filtering phase recovers singular points and removes artifacts on silhouettes by averaging depth data using neighborhood pixels on which both depth difference and RGB s... https://www.cosmeticssquadets.shop/product-category/face-serum/
