ABSTRACT:
An image analyzer system includes a pipeline of individually programmable neighborhood transformation stages. Programming of the stages is accomplished by way of coded command signals which are either of a local or global type. Global commands propagate down the pipeline to all of the stages whereas local commands are utilized to program only selected stages. Once the stages are programmed the image data may be transferred over the same bus previously utilized to carry the programming instructions. In the preferred embodiment, control lines are employed to indicate whether image data or programming instructions are being transferred over the bus.
