We propose an algorithm for deinterlacing of interlaced video sequences. It successively builds approximations to the deinterlaced sequence by weighting various interpolation methods. A particular example given here uses four interpolation methods, weighted according to the errors each one introduces. Due to weighting, it is an adaptive algorithm. It is also time-recursive, since the motion-compensated part uses the previously interpolated frame. Furthermore, bidirectional motion estimation and compensation allow for better performance in the case of scene changes and covering/uncovering of objects. Experiments are run both on “real-world” and computer generated sequences. Finally, subjective testing is performed to evaluate the quality of the algorithm
