Clustering Dynamic Textures with the Hierarchical EM Algorithm
The dynamic texture (DT) is a probabilistic generative model, defined over space and time, that represents a video as the output of a linear dynamical system (LDS). The DT model ...

Constraining Human Body Tracking
Our paper addresses the problem of enforcing constraints in human body tracking. A projection technique is derived to impose kinematic constraints on independent multi-body motion...

Estimation of Arbitrary Camera Motion in MPEG Videos
Several algorithms have been proposed to solve the problem of camera motion estimation in digital videos. However, the distinction between translation along the xaxis (y-axis) and...

Non-Iterative Approach to Multiple 2D Motion Estimation
We present an innovative method estimating multiple 2D motions from uncalibrated images. Our approach robustly and non-iteratively estimates multiple 2D parametric motions, affine...
