METHOD FOR DETECTING MOVING OBJECTS AND DETERMINING PARAMETERS THEREOF Russian patent published in 2012 - IPC G06T7/20 

FIELD: information technology.

SUBSTANCE: phase decompensation (phase-energy characteristic) arises during movement of an object due to the displacement section. The phase value at which decompensation arises is the maximum phase; it is characterised by a clear-cut maximum or minimum, after zero values, corresponds to the edge of the object furthest from the middle of the row (column); in determining the direction of displacement, using information on coordinates of the object, by comparing maximum phase difference values of phase-energy (hereinafter maximum phase) characteristics for a sequence of three frames; in determining contrast of the object relative the background, using defined values of coordinates and direction of movement of the object; in determining displacement of the object (in pixels), using information on coordinates and direction of movement of the object, by comparing spectral density values corresponding to the maximum phase.

EFFECT: high efficiency of detecting moving objects and determining motion parameters thereof in low luminance conditions, including low-contrast and small-sized objects on the complex inhomogeneous background of a series of digital images.
