Image Block Motion Estimation Using Fit By Generalized Discrete Orthogonal Polynanials
Jong Soo Lee · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1986
Fitting an image block with ordinary discrete orthogonal polynomials results in large errors at and around the block center. However, using discrete orthogonal polynomials gen-eralized with a normal weight, we have smaller errors at and around the center. In this paper, we show a technique estimating block motion in two successive image frames using the generalized polynomials. The technique fits blocks of two image frames with the polynomi-als and derives constraints from which translational motion components can be determined.
