The author examines several motion estimation algorithms operating on a block by block basis. These algorithms are considered with respect to their accuracy for various degrees and types of motion, the computation required to obtain the motion estimate and their suitability for use in an adaptive hybrid coding scheme. The algorithms considered can be categorised into one of two groups, matching techniques and those methods employing spatial-temporal differentials. Algorithms within these categories have been compared for four real sequences displaying a variety of scene content and degree of movement and for six synthetic sequences. For the synthetic sequences only uniform translation has been considered.
