| 摘 要： | De-interlacing is very important when converting interlaced pictures to progressive pictures in format conversion. Multi-formats digital broadcast and progressive display requires the de-interlacing technique. An adaptive weight de interlacing method is proposed. It combines motion compensation technique with directional-based spatio-temporal filter efficiently. Experiment results indicate that the method can keep edge continuity and sharpness effectively, reduce the artifacts in motion areas, and shows better visual performance when the estimated motion vectors are inaccurate.
