Abstract A new probabilistic method of improving low-contrast and small sized objects reliable detection on the images with hardly formalized background, under the conditions of full a priori uncertainty is considered. The notion of the Chernoff’s bound in the case of an object’s brightness and background arbitrary ratio basing on more peculiar Markov Random Field model and statistical approaches of classification and detection of objects is widened. The proposed dynamic segmentation allows forming binary fields with signs of objects’ motion on the gray or colour image sequence that for measuring parameters of motion in real time could be used.
