Cardboard People: A Parameterized Model of Articulated Image Motion
We extend the work of Black and Yacoob on the tracking and recognition of human facial expressions using parameterized models of optical flow to deal with the articulatedmotion of...

Modeling complex luminance variations for target tracking
Lambert's model is widely used in low level computer vision algorithms such as matching, tracking or optical flow computation for example. However, it is well known that thes...

Self-Calibration from Optical Flow and Its Reliability Evaluation
An algorithm is presented for 3-D reconstruction from optical flow observed by an uncalibrated camera. We show that by incorporating a statistical model of image noise, we can not...

Telecentric Optics for Free-Space Optical Link
-- We describe a telecentric optical system for free-space multichannel optical interconnects. The targeted aggregate data rate is 240Gb/s. We have a unique implementation of telec...

Multimodal speaker diarization using oriented optical flow histograms
Speaker diarization is the task of partitioning an input stream into speaker homogeneous regions, or in other words, to determine "who spoke when." While approaches to t...
