Abstract
Piecewise linear (PWL) models are very attractive for image processing due to their simplicity and effectiveness. A new filtering architecture adopting parameterized PWL functions is presented. The proposed approach takes into different account the correlation between the central pixel of a moving window and its neighbors in two subwindows. As a result, the filtering errors can be reduced and a very accurate restoration of the image data can be achieved. The sensitivity to a change of the parameter settings is also investigated
