High-speed digital image processor with special-purpose hardware for two-dimensional convolution.
A high-speed digital image processor combined with a flying spot scanner and special purpose hardware for two-dimensional convolution has been developed. This processor is applicable to image enhancement, image restoration, and feature extraction. The parallel and/or serial architectures of the processor enable digital image processing for a high-resolution image at a fast process rate. Realization of the high-speed operation of two-dimensional convolution is greatly due to the special scanning method of a flying spot scanner. This processor is well suited to process the image recorded on the photographic film by means of the two-dimensional digital filtering technique. Some experimental results are given to verify the capability of the developed processor.
