In this paper we introduce a working generalization of the theory of Gröbner bases for algebras of partial difference polynomials with constant coefficients. One obtains symbolic (formal) computation ...

Finite difference is a numerical method used to approximate derivatives by calculating differences between function values at discrete points. It is commonly applied in physics and engineering to ...

Motion search is by far the most complex operation to be performed in a video encoder. This paper proposes a novel fast matching algorithm to help speed up the computation of the matching (distance) ...

In this paper, we present a new sorting-based partial distortion elimination (PDE) algorithm for fast optimal motion estimation. By analyzing the contributions to the true sum of absolute differences ...
