We review how IR images differ from visible images, emphasize the importance of using a variety of IR images for assessing the utility of various algorithms for displaying them, and develop a gamma function suitable for 8-bit display on Sun workstation monitors. For globally monotonic mapping of wide dynamic range IR imagery to 8 bits for display, we describe and compare direct scaling, histogram equalization, histogram projection, and several hybrid ...
the effect noise, including system noise, background noise, and cell- to-cell nonuniformity (spatial noise), is mathematically treated and experimentally verified for staring-mode infrared cameras. we present data showing that neither variations in detector spectral response nor excess low frequency noise can be fully corrected using existing nonuniformity correction techniques. furthermore, we show that even the small amounts of nonuniformity that persist after the application of correction algorithms will significantly degrade ...
