FIELD: physics.
SUBSTANCE: invention relates to image processing, and more specifically to estimation of motion vectors in a sequence of photographic or video images. Method for estimating motion on an image field comprises steps of: obtaining at least two images from an input bit stream comprising a plurality of images, performing preliminary processing of images, estimating a map of M parameters of a motion estimation algorithm (ME) for said pair of images and performing motion estimation for said pair of images; wherein said preprocessing comprises, at least, brightness adjustment. applying preconfigured prediction model of spatial parameters of motion estimation algorithm to said pair of images, storing said map of parameters of the motion estimation algorithm in the form of an array having dimensions corresponding to the desired field of motion vectors (MVF); motion estimation is performed depending on the above motion estimation algorithm parameters map and the motion vector field is output in the form of two-dimensional (2D) array of displacements from the position of each pixel on the first image to at least one position of the corresponding pixel on the second image in the said pair of images. Also disclosed is a system which realizes this method.
EFFECT: high accuracy of estimating motion vectors over an image field.
