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...

An Estimation-Theoretic Interpretation of Video Rate Distortion Optimization with Lagrangian Formulation
Rate distortion optimization with Lagrangian formulation is widely used in video encoder control and has proved effective in achieving a good trade-off between coding efficiency a...
