Fast bilateral filtering by adapting block size
Direct implementations of bilateral filtering show O(r2 ) computational complexity per pixel, where r is the filter window radius. Several lower complexity methods have been devel...

Discriminatively Trained Particle Filters for Complex Multi-Object Tracking
This work presents a discriminative training method for particle filters in the context of multi-object tracking. We are motivated by the difficulty of hand-tuning the many mode...

Recognition of Repetitive Sequential Human Activity
We present a novel framework for recognizing repetitive sequential events performed by human actors with strong temporal dependencies and potential parallel overlap. Our solutio...

Unsupervised Face Alignment by Robust Nonrigid Mapping
We propose a novel approach to unsupervised facial image alignment. Differently from previous approaches, that are confined to affine transformations on either the entire face o...

Projective Rotations Applied to a Pan-Tilt Stereo Head
A non-metric pan-tilt stereo-head consists of a weakly calibrated stereo rig mounted on a pan-tilt mechanism. It is called non-metric since neither the kinematics of the mechanism...
