Spatial tracking of human head position based on the video frames analysis

Abstract: A spatial tracking system of PC user head position is suggested. The system operates on frames captured by video camera, and includes the following operation stages: detection of user’s front face view, semi-automatic initialization of head model, tracking of inter-frame head movement with the use of gradient-based optimization method. As a head model, 3D cylinder surface with applied 2D texture has been used.
