Figure 16From: Layer-based sparse representation of multiview imagesDe-noising subjective evaluation. (a) Tsukuba light field corrupted with AWGN (PSNR 18.6 dB). (b) De-noised dataset using proposed sparse representation (PSNR 28.65 dB). (c) De-noised dataset using SURE-LET OWT applied to each image independently (PSNR 27.16 dB).Back to article page
