Abstract

Image processing applications are computationally expensive. The paper shows that the computational time required for an application such as correlation can be considerably reduced by using a hierarchy of images. Even with these optimisation techniques, speeds do not approach real time on a uniprocessor system, but significant speed increases can be obtained by using a multi-processor system. It is shown that choosing the correct processor for the desired application is an important decision and that for correlation a digital signal processor provides superior performance over conventional processors.
