*** REPLACE THIS LINE WITH YOUR MESSAGE *** Title: Image processing by constant volume operators. Speaker: John I. Yellott, Jr. Affiliation: University of California, Irvine. Time and date: 2 PM, Thursday January 23, 1986. Place: Life Sciences Bldg. 239, Conference Rm 177. Contact: A. Ahumada, x6257, Mail Stop 239-3. Abstract: A class of image processing operators is described which can take images with a large variation in quantum catch per pixel and produce output images with a relatively constant signal-to-noise ratio per pixel. These simple operators automatically provide spatial summation for noise reduction at low signal levels and high-pass filtering for signal compression at high signal levels. These operators are shown to obey several basic psychophysical "laws" of the human visual system.
