Abstract
The present invention is embodied in a system and method for automatically estimating the orientation or pose of an object, such as a human head, from any viewpoint and includes training and pose estimation modules. The training module uses known head poses for generating observations of the different types of head poses and the pose estimation module receives actual head poses of a subject and uses the training observations to estimate the actual head pose. Namely, the training module receives training data and extracts unique features of the data, projects the features onto corresponding points of a model and determines a probability density function estimation for each model point to produce a trained model. The pose estimation module receives the trained model and an input object and extracts unique input features of the input object, projects the input features onto points of the trained model and determines an orientation of the input object that most likely generates the features extracted from input object.
