Enhancing Matrix Completion Using a Modified Second-Order Total Variation

Figure 6

Visual results on Lenna image with 60% missing ratio by different algorithms. (a) Original image. (b) Randomly masked image. (c) IRLS: PSNR=22.91dB, SSIM=0.707. (d) PSSV: PSNR=23.21dB, SSIM=0.696. (e) LTVNN: PSNR=24.91dB, SSIM=0.853. (f) SPC-TV: PSNR=25.24dB, SSIM=0.801. (g) SPC-QV: PSNR=27.50dB, SSIM=0.898. (h) Ours: PSNR=28.96dB, SSIM=0.936. The figure is better viewed in zoomed PDF.
