摘要

Digital enhancement techniques applicable to Direct Readout (APT) Meteorological satellite images were developed,and computer routines designed and tested. Areas covered include melding of geographic grids with digital images;display of image arrays at mercator and polar stereographic projections;Fast Fourier Transform subroutine;digital filters for low frequency reduction,high frequency spatial enhancement,single frequency,and edge search and sharpen;and gray scale histograms.
