Abstract

VAP is a novel digital video array processor for local image transforms working at TV pixel rates in conjunction with an image memory having simultaneous but independent read/ write capability. A programmable system of delay lines is used to access 16 selectable pixels within a local neighbourhood. This information is reduced in a pipeline structure similar to a binary tree, the nodes of which are look-up tables with two inputs and one output. Transformations on whole images may thus be iterated at the TV frame rate. Applications include image preprocessing to allow segmentation by texture, edge detection, etc. but also binary image transformations such as erosion, dilatation, thinning and others.
