In public venues, crowd size is a key indicator of crowd safety and stability. Crowding levels
can be detected using holistic image features, however this requires a large amount of …

For a responsive audio art installation in a skylit atrium, we introduce a single-camera
statistical segmentation and tracking algorithm. The algorithm combines statistical …

The development of technologies for reliable tracking of pedestrian trajectories in public
spaces has recently enabled collecting large data sets and real-time information about the …

This paper presents an experimental study on pedestrian bidirectional streams and the
mechanisms leading to spontaneous lane formation by examining the flow formed by two …

Existing crowd counting algorithms rely on holistic, local or histogram based features to
capture crowd properties. Regression is then employed to estimate the crowd size …

0004 Recognition of human actions from video streams has many applications in the
Surveillance, entertainment, user interfaces, Sports and Video annotation domains. Given a …

This article deals with the problem of classification of human activities from video. Our
