ABSTRACT:
A method is provided for selecting a filter for interpolating a target pixel for reducing noise in an image. The method comprises the following steps. A plurality of pixels along a predetermined contour is compared with a plurality of predefined patterns. The patterns represent visually significant patterns possible along said contour. A filter is selected from a predefined set of filters in accordance with the results of the comparison.
