Adaptive motion model selection using a cubic spline based estimation framework
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...

Dither-modulation data hiding with distortion-compensation: exact performance analysis and an improved detector for JPEG attacks
The binary Distortion Compensated Dither-Modulation (DCDM), which can be regarded to as a baseline for quantizationbased data-hiding methods, is rigorously analyzed. A novel and a...

Using an adaptive VAR Model for motion prediction in 3D hand tracking
A robust VAR-based (vector autoregressive) model is introduced for motion prediction in 3D hand tracking. This dynamic VAR motion model is learned in an online manner. The kinemat...
