ABSTRACT:
A method and apparatus for improving the quality of a composite video signal and a method and apparatus for decoding the composite video signal. The method for improving the quality of the composite video signal respectively detects edges from a luminance information signal and a chrominance information signal separated from the composite video signal, detects an artifact region using the detected edges, and filters the detected artifact region. Accordingly, an artifact can be effectively removed while preserving edge information and detail information of an image to improve picture quality.
