Recent Nonlocal Means filter (NLM) [1] is lack of mean conservation property, that is, image can have different mean before and after being processed. It is not suppose to happen ...
The present paper contributes two novel techniques in the context of image restoration by nonlocal filtering. Firstly, we introduce an efficient implementation of the nonlocal mean...
We present a new method aimed at restoring structures in 3D US images. In our approach, 3D US data acquired with tilt devices is resampled into cylindrical coordinates with the pu...
