Interpolation of skipped image frames for image sequence coding

This work presents several algorithms for temporal interpolation which permit frame skipping with less degradation in quality of the interpolated frames. In the developed algorithms there is a trade-off between this quality and the amount of additional side-information used. Smoothing of the motion-vector field, based on a selective median filter is intended to prevent blocking effects created by sub-optimal block matching or stray motion. The performance of the proposed algorithms is compared in image-sequence coding simulations
