Abstract
In this paper we present a technique for bit-rate reduction in the H263 coder by the introduction of perspective transformation in the advanced prediction option of motion compensation. It is based on the use of the available displacement vectors for estimating the image warping. Since block matching gives not reliable estimates of the warping an adaptive technique discarding inconsistent transformations has been adopted.
