MOTION ESTIMATION WITH MORE THAN 2 FRAMES

This paper reports on the development of a general motion estimation system based on using three or more frames. The relevant portion of the sequence is treated as a whole, thus simplifying the process of estimating the motion parameters, and enabling the computation of the motion parameters in terms of the natural center of motion. The paper presents a general description of this motion estimation method, with the derivation of motion equations for three cases (3 points in 3 frames, 2 points in 4 frames, and 1 point in 5 frames). Results are given for real and synthetic images for the case of 1 point in 5 (and 6) frames. © 1990 IEEE
