Abstract
A procedure is outlined, based on Fourier transformation, for the primary processing of band-specific images via laser scanning, in particular the enhancement of various types of spatial structures for image interpretation purposes. Stages in the process include: (a) identification of the portions of an initial, original image that are of interest to the user; (b) reduction of additive and multiplicative errors resulting from variations in intensity of the laser beam; (c) correction of band-specific imagery based on calibration data of the coherent optical transform device and the use of digital filters; (d) reduction in image processing time and data storage requirements through elimination of extraneous data. The procedure is demonstrated using a 1:56,000-scale aerial photograph as an initial image. Translated from: Geodeziya i kartografiya, 1986, No. 7, pp. 32-35.
