TRANSMISSION OF DATA ON PHOTOELECTRONIC MODULE IR IMAGES VIA LOW-FREQUENCY COMMUNICATION CHANNELS ON THE BASIS OF WAVELET TRANSFORMS
ABSTRAKT
An algorithm of frame wavelet compression of IR image data, received by multicomponent photodetectors, to be transmitted via low-bit-rate communication channels (up to 3−5 Mbps) is considered. The proposed algorithm takes into account the drift of sensitivity of photoelectronic module CMT matrix elements in working conditions, which increases the interval between geometric noise calibrations to several hours.
