FIELD: digital image processing technology, in particular, processing of signals for selecting moving objects in a series of television images.
SUBSTANCE: in accordance to the invention, image turning angle of previous frame is determined relatively to standard image, increase of precision of calculation of shift parameters up to shares of pixel, change of standard image depending on computed values of shift and turn, shift of background image for integer number of pixels, turn of image around current frame around image center and following shift of turned image for fractional number of pixels, computation of value of threshold value with consideration of turbulence of atmosphere, vibration of image sensor and error when determining parameters of shift and turn, inter-frame filtration of threshold processing results.
EFFECT: increased precision of object selection due to resistance to spatial distortions.
