Research of image processing methods in publishing output systems

摘要

For automatic processing of images in publishing output systems it is necessary to pre-reduce the noise level, to increase sharpness, to exclude the possibility of a moire, that is, to improve the quality of the image before printing. There are the results of using the Fourier transform for simple figure images. The amplitude spectrum values for blurry and detailed images are considered, and the methods of automatic processing of images in laser-type publishing systems are also shown.
