Abstract

A review of activities in digital image processing in Japan is presented, with concen-tration upon image restoration and image synthesis. Effects of the experimental errors on the restored images are examined through computer simulation of Wiener filtering and an experimental result considering these effects is shown. An optimum filter to restore the degraded image due to blurring of the system and signal-dependent noise is obtained, based on the theory of linear least-squares filtering. Utility of the method of least-squares to suppress the noise amplification during restoration process will be demonstrated through on-line digital image restoration of the motion blurred image by use of a mini-computer system and restoration of diffraction-limited noisy image. Technique of digital image synthesis is applied to evaluate the image of a complex object formed by a partially coherent optical system.
