An ℓ0-overlapping group sparse total variation for impulse noise image restoration

作者:

Highlights:

• The proposed model robustly eliminates impulse noise and the staircase artifacts.

• The proposed model efficiently solves the non-convex model.

• Significantly better results for both image denoising and deblurring.
