Hand Depth Image Denoising and Superresolution via Noise-Aware Dictionaries

Figure 5

Denoising additive Gaussian noise using traditional OMP and NAOMP (both without the filtering phase). Left: hand depth images with artificial noise. Middle: denoised images using traditional OMP. Right: denoised images using NAOMP. Rows 1–3: 0.5%, 2%, and 5% of noise for hand 1; rows 4–6: 0.5%, 2%, and 5% of noise for hand 2; rows 7–9: 0.5%, 2%, and 5% of noise for hand 3.
