ABSTRACT OF THE DISCLOSURE A system and method for processing image data in a graphics display system using parallel processing. A source image represented as an array of image pixel values is convolved by a kernel function to enhance selected features and assist in image analysis. Bi-linear interpolation is implemented to preserve picture quality when a source image is enlarged or reduced. A series of processing elements connected in parallel are used to speed image transformation and interpolation. The application of convolution is divided between the processors so that the processing with adjacent pixels overlaps and output image pixels are generated in fewer machine cycles. A pipeline architecture continually processes values from the parallel processors through validation and conversion to generate the final image.
