An ℓ0-overlapping group sparse total variation for impulse noise image restoration
Total variation (TV) based methods are effective models in image restoration. For eliminating impulse noise, an effective way is to use the ℓ1-norm total variation model. However, the TV image restoration always yields staircase artifacts, especially in high-density noise levels. Additionally, the ℓ...
