An interactive image processing system based on the minicomputer, INTERDATA 7/32, has been developed. This system is adaptable for developing a variety of image processing algorithms efficiently. Features of the system are that (1) it is composed by centering on the main memory of the minicomputer and no buffer memory is equipped, (2) it has hardwares for displaying coded and/or continuous-tone images efficiently, (3) it is equipped with a hardware to be able to execute two-dimensional convolution at high speed, and (4) data acquisition, data display and data processing can be made at high speed for a high resolution image. In order to transfer high resolution image data at high speed between the main memory and the developed hardwares or peripherals, direct memory access facilities are adopted together with time sharing technique. Applicability of the developed system is demonstrated through experiments for simple pattern analysis and for iterative image restoration for a linearly degraded image.
