Start year: 2009

Summary: Automated recognition of certain human activities in surveillance videos can prove critical for the security and safety of environments. To date, the effectiveness of automated activity recognition has been limited by ''''the curse of dimensionality'''' that is the difficulty of learning adequate activity models in high-dimensional spaces. This project will propose novel non-parametric approaches and dimensionality-reduction techniques to tackle this problem simultaneously from two sides. The outcome of this project will be an activity recognition technology suitable for use in real environments.
