abstract = "Recently, investigations on medical imaging have been indicating a
strong correlation between cases of cancers and the increasing
number of Computed Tomography (CT) exams, mainly due to high
radiation doses to which patients are exposed during the data
acquisition process. Thus, there is a need to reduce the radiation
doses whereas still keeping satisfactory quality images for
diagnosis. In this paper, we propose to filter noise in CT images
using contextual versions of Wiener Filter such as Generalized
Wiener Filter (GWF) and Non Local Means approach for parameter
estimation. Experiments show that the proposed methods are
promising, since they provide good results with no significant
increase in the computational cost.",
