Abstract
Motion compensation de-interlacing is expected to be better than linear techniques; but all the block-based motion compensation de-interlacing methods cause block artifacts. An algorithm is proposed to reduce the deficiency of motion-compensated interpolation by adaptive hybrid de-interlacing method. A spatio-temporal tensor-based approach is used to get more accurate motion field for de-inter-lacing. Motion vector is assigned for each position with pixel precision; and the block artifact is reduced significantly. To deal with the artifacts introduced by motion-compensation when the motion estimation is incorrect, linear techniques are considered by adaptive weighting. Directional filter is adapted to preserve details and the edge discontinuity could be eliminated greatly.
