Summary on Grant Application Form |

Image compression is a vital technology in the realisation of the information highway and motion estimation (ME) is a key aspect of image compression systems. Although simple in principle, real-time ME processors are notoriously difficult and expensive to realise because of their huge computational requirements. As a result, the ME processor is the most complex and power hungry component of a digital video codec.This project is concerned with the application of analogue circuits to ease the implementation complexity of ME processors for digital video encoding. Using a new architecture for ME processor design and current-mode analogue circuits, large reductions in size, power dissipation and implementation cost can be achieved compared to digital implementations. To demonstrate the new approach, a compact, low power, analogue ME processor will be designed, built and evaluated which could be readily extended to meet the requirements of commercial digital video encoding. Such a ME processor is particularly important in portable video systems where size and power dissipation are incompatible with digital implementations.
