Convolver for Pipelined-Image Processor
Abstract
3 x 3 convolver produces weighted sum of nine contiguous picture elements in square. Data processed through convolver at video scanning rate of current raster line. Two previous lines stored in external buffers (N-3)element delays. Specific choice of convolution weights determines whether convolver performs smoothing, spatial-frequency filtering, edge detection, or other forms of image processing.
