ROBUST HEAD TRACKING METHOD USING ELLIPSOIDAL MODEL IN PARTICLE FILTERS

摘要

A head tracing method in a particle filter using an ellipsoid model performing fast tracking a particle for the predicted place is provided to trace the operation head through the small number of particles by generating particles and estimating the movement. An ellipsoid model is initialized(100). A movement is predicted by using an adaptive state transition model(110). Particles are generated through prediction(120). The most good particle is determined. A full 3D motion recovery process is utterly performed in the most good particle. The observation model is updated.
