Convergence Theorems for the Non-Local Means Filter
Qiyu Jin, Ion Grama, Quansheng Liu
In this paper, we establish convergence theorems for the Non-Local Means Filter in removing the additive Gaussian noise. We employ the techniques of "Oracle" estimation to determin…

Optimal Weights Mixed Filter for Removing Mixture of Gaussian and Impulse Noises
Qiyu Jin, Ion Grama, Quansheng Liu
According to the character of Gaussian, we modify the Rank-Ordered Absolute Differences (ROAD) to Rank-Ordered Absolute Differences of mixture of Gaussian and impulse noises (ROADG…

A New Poisson Noise Filter based on Weights Optimization
Qiyu Jin, Ion Grama, Quansheng Liu
We propose a new image denoising algorithm when the data is contaminated by a Poisson noise. As in the Non-Local Means filter, the proposed algorithm is based on a weighted linear…
