A combined higher order non-convex total variation with overlapping group sparsity for Poisson noise removal
Poisson noise removal is a fundamental image restoration task in imaging science due to the Poisson statistics of the noise. The total variation (TV) image restoration has been promising for Poisson noise removal. However, TV-based denoising methods suffer from the staircase artifacts which makes th...
