From extension of Loop's approximation scheme to interpolatory subdivisions
The minimum-supported bivariate C2-cubic spline on a 6-directional mesh constructed in our previous work [2] can be used to extend Loop's approximation subdivision scheme to ...

An optimal quadtree-based motion estimation and motion-compensated interpolation scheme for video compression
Abstract—In this paper, we propose an optimal quadtree (QT)based motion estimator for video compression. It is optimal in the sense that for a given bit budget for encoding the d...
