In this paper we propose a rate-distortion optimized motion estimation algorithm that is built upon a quadtree structure. Each node of the quadtree represents a block in the curre...

We propose a quad-tree scheme for obtaining sub-pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated ...

A block based video coder that supports multiple motion models is proposed. Apart from the typical translational motion model, we employ parametric models to more accurately repre...

Thin plate spline (TPS) transformations have been applied to non-rigid shape matching with impressive results. However, existing methods often use a sparse set of point correspond...
