Motion compensating prediction of moving pictures

摘要

Motion compensating prediction of moving pictures using an interpolation comprises performing time recursive motion compensation of a reference picture (s '(t-1)) in which the pixels are displaced in accordance with their motion vectors (L Ò d(t-1)). The motion compensated items of pixel information are inserted into an interpolation grid between the pixels of the reference picture (see figs. 4 and 5). In this manner, temporally past items of pixel information are taken into account in addition to spatially adjacent pixels to produce an interpolated picture (s'u (t-1)).
