Fast Joint Estimation of Silhouettes and Dense 3D Geometry from Multiple Images
—We propose a probabilistic formulation of joint silhouette extraction and 3D reconstruction given a series of calibrated 2D images. Instead of segmenting each image separately i...

A real-time hand tracker using variable-length Markov models of behaviour
We present a novel approach for visual tracking of structured behaviour as observed in human–computer interaction. An automatically acquired variable-length Markov model is used...

Fast detection of arbitrary planar surfaces from unreliable 3D data
Abstract— Man-made real-world environments are dominated by planar surfaces many of which constitute behaviorrelevant entities. Thus, the ability to perceive planar surfaces is v...
