Robust audio-visual person verification using Web-camera video
This thesis examines the challenge of robust audio-visual person verification using data recorded in multiple environments with various lighting conditions, irregular visual backgrounds, and diverse background noise. Audio-visual person verification could prove to be very useful in both physical …

An Intelligent Guidance System for Computer-Guided Surgical Training
… system was implemented first using a single web camera. Also, an instrument tracking system was designed to support the guidance based on kinematic equations with particle swarm optimization (PSO). For the force guidance system, self-adjusting fuzzy sliding mode controllers are proposed with …
