An Intelligent Guidance System for Computer-Guided Surgical Training
… 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 virtual fixtures. To …

Methods for multiple pitch tracking and instrument separation from monaural polyphonic recordings
… Analysis results can be in the form of source tracking, where instrument pitch tracks and their weights are estimated from a sound mixture throughout time, or they would be in the form of source separation where individual sources are extracted from the mixture. Both problems are addressed in …

Vision Based Surgical Tool Tracking with Robot Kinematics Prior
… execute high-level surgical tasks by commanding instruments controlled by precise robotic devices. Several advantages arise. To name a few: (1) achieved precision is beyond that of human dexterity alone (2) a greater number of kinematic degrees of freedom are possible at the surgical tool tip (3) …
