Abstract
An algorithm based on motion compensation uses a temporal support of five fields of video to produce a progressive frame. The moving average of the motion compensated field lines temporally adjacent to the field to be de-interlaced are used, after a non-linear filtering, as the missing lines to complete the progressive video frame.
