Abstract

Onboard analysis of remotely sensed images can help in the case of real time processing of high resolution Earth images, giving the possibility of selecting frames, containing essential information, for transmission to ground station (for reducing the data flow). One of possible methods of frames selection is image texture analysis on base of spatial frequencies spectrum processing. The questions of incoherent light source usage in the optoelectronic Fourier spectrum analyser are considered. Using of incoherent light source of specific size and shape makes it possible to provide an optimal spatial filtering of the spectrum, reduce a sensitivity to phase distortions and obtain a compact and rugged design of the device. Special algorithm of spectrum image digitising is developed to enlarge a range of spatial frequencies to be processed and maximise the photosensitivity. The algorithms for texture properties recognition are developed and tested using prototype incoherent Fourier spectrum analyzer.
