METHOD AND APPARATUS FOR EDGE ENHANCEMENT CONSIDERING SINGULAR POINTS

摘要

A method of and apparatus for edge enhancement considering singular points are provided. The method of edge enhancement includes: determining a first gain from the input image; detecting a singular point distinguishable from an edge from among pixels of the input image; based on the detection result of singular points, determining a second gain for edge enhancement processing; and multiplying the first gain by the second gain to generate a resulting edge-enhanced image.
