An analogue approach to the design of motion estimators for digital video encoding

We propose a new architecture which enables a motion estimation (ME) processor to be constructed using analogue components. At present, due to the arduous scale and nature of the computations required in digital hardware realisations, the ME processor is invariably the most complex and expensive component of a modern video codec. Our preliminary results indicate that very considerable reductions in size, power consumption and hence cost are available using our proposed method
