Poisson Noise Removal Scheme Based on Fourth-Order PDE by Alternating Minimization Algorithm
To overcome the staircasing effects introduced by the TV regularization in image restoration, this paper investigates a fourth-order partial differential equation (PDE) filter for removing Poisson noise. In consideration of the slow convergence property of the classical gradient descent method, we a...
