Abstract
A method for interpolating a target pixel from a plurality of source pixels in a high contrast image. The method comprises the following steps. A window of the plurality of source pixels is examined and compared with a plurality of predefined conditions for determining if a structure of significance is present within the window. A filter configuration is selected from a plurality of filter configurations in accordance with results of the comparison. The selected filter is applied to the source pixels for interpolating the target pixel. If the structure of significance is detected in the window, the selected filter best preserves the structure.
