Abstract : 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.
