ABSTRACT:
A system and method that produces a spatial average for interlaced video in a deinterlacer. The system detects edges in the video images and determines the angle at which the edges are oriented based on the gradient in the x-direction and the gradient in the y-direction. The direction of the edge is determined using the angle information of the edge. The system may also determine the strength of the edge. Based on the determined characteristics of the edge a filter may be selected to produce a spatial average of the edge in the image.
