Multiprocessor techniques for use in low-cost vision systems

Many applications of artificial-vision systems are complex and computationally expensive and so demand powerful and therefore expensive processing units. However, there is also a place for low-cost systems. Artificial vision systems for use in manufacturing industry may need high speed response, but not all manufacturing applications do. High resolution is sometimes needed, but often working with low-resolution images can give useful results. Cost is often of great importance with systems to be used in manufacturing. The paper describes the early stages of an investigation into multi-processor systems for image-processing which do not involve large expenditure
