Poissonian Image Deconvolution via Sparse and Redundant Representations and Framelet Regularization
Figure 6
Restoration of the Lena image. (a) Blurred by using the customized kernel and then corrupted by Poisson noise (PSNR = 26.8674 dB). (b) Restored image by the PIDSB-FA method (PSNR = 30.62 dB). (c) Restored image by the LD-TV method (PSNR = 30.66 dB). (d) Restored image by the proposed method (31.74 dB).
