Title:       Towards Improving the Robustness of Gesture Recognition
              Systems: Addressing Large Vocabularies and Cluttered Scenes

Abstract:

Automated computer-vision based recognition of human gestures is an
important task for many real-world domains, such as human-computer
interaction, sign language education, and content-based access in
large video databases. This talk presents methods that aim to improve
recognition accuracy under two challenging scenarios. The first
scenario is situations where the gesture is performed in front of a
complex background, that may include significant motion and
distracting objects. In such complex scenes, human body detection and
tracking modules are error-prone and do not provide clear, unambiguous
results. The key philosophy underlying our gesture recognition method
is that recognition modules should be explicitly designed to operate
using the faulty and/or ambiguous results of the lower level
modules. The second challenging scenario is recognition of a large
vocabulary of gestures. We present work towards a system that lets
users look up the meaning of an unknown sign in American Sign
Language. In that system, the user performs the sign of interest in
front of a webcam (or just submits a pre-recorded video of that sign),
and the system retrieves and displays the most similar signs from the
system dictionary.
