Gradient schemes for robust FFT-based motion estimation

Georgios Tzimiropoulos, Vasileios Argyriou

Abstract

In this work, the focus is on gradient-based correlation schemes which constitute an alternative to phase correlation for FFT-based motion estimation. In particular, our contribution is threefold. First, we present an analysis which highlights the key features of gradient schemes. Second, we introduce an illumination invariant to gradient correlation. Third, we provide a comparison of gradient schemes in the application of block matching for video coding and draw several useful observations and conclusions.
