Poissonian Image Deconvolution via Sparse and Redundant Representations and Framelet Regularization
Figure 4
Restoration of the brain image. (a) Degraded image is blurred by uniform kernel of size and contaminated by Poisson noise with (PSNR = 23.20 dB). (b) Restored image by the PIDSB-FA method (PSNR = 28.82 dB). (c) Restored image by the LD-TV method (PSNR = 28.08 dB). (d) Restored image by the proposed method (PSNR = 29.51 dB).
