Patent abstract
The present invention relates to a method and apparatus for detecting an edge in an image or video. The present invention can detect an edge more quickly by detecting edge information by using the absolute values and codes of two coefficients (AC01, AC10) in the DCT domain. In addition, the present invention can detect a more rapid and accurate edge by using the edge detection method using two coefficients as a pre-filter and using the edge detection method using a spatial filter as a post-filter.
