Extraction of the motion indications in the sequence of images

Abstract

The problem of extraction of the motion indications, i.e. coordinates and parameters of the motion in the sequence of images is considered. The analysis of the images under consideration is based on the use of a cyclic group with the operation of dyadic shift on the finite intervals. The majority sequences on the dyadic group are formed with the help of the dyadic-shift operations. The whole set of sequences is obtained by specifying the coordinates of vectors. The class of these sequences can be obtained by the majority addition of the Walsh functions. Detection and extraction of the dynamic object is implemented through intermediate calculations of the majority sequences describing the moving object. The correlation method for extracting the motion indications in the sequence of images using the majority sequences determined on the dyadic group has been considered. Such an approach makes it possible to obtain the precision characteristics of the processing which are near to the optimum ones.
