System and method for scaling images

摘要

A system and method are provided for calculating a target pixel for scaling an image comprising a plurality of source pixels. A contour is determined in the image using at least one of a first set of predetermined parameters. A filter tap configuration is adaptively selected from a predefined set of filter tap configurations in accordance with the determined contour. The predefined set of configurations includes a plurality of non-linear filter tap configurations. The target pixel is calculated by selectively convolving ones of the plurality of source pixels along a locus of the selected filter tap configuration with a weighting factor, and combining the convolved pixels.
