Image Restoration by a Mixed High-Order Total Variation and Regularization Model

Figure 2

The restoration results for different parameters. (a) Original image. (b) Observed image: the “Lena” image is blurred by Gaussian blur with size “9 9” and added the Gaussian noise with BSNR=35. (c) The restoration result with , , and (SNR = 22.04). (d) The restoration result with , , and (SNR = 19.97). (e) The restoration result with , , and (SNR = 22.51). (f) The restoration result with , , and (SNR = 22.49). (g) The restoration result with , , and (SNR = 19.73). (h) The restoration result with , , and (SNR = 16.88). (i) The restoration result with , , and (SNR = 22.92).
