Abstract:
1. A method for detecting head pose of an individual comprises the steps of: capturing a pair of images of a person from a pair of stereo cameras; scanning the pair of images simultaneously to locate at least one component in the pair of images, wherein scanning comprises: using a window to analyze a section of each of the images, calculating a predetemined set of features and a classification score for the new window, determining if the classification score is above a predefined threshold, if the classification score is above the predefined threshold, determining that a component has been located, and if a feature score is below the predefined threshold, sliding the window in the image to an adjacent position and calculating a feature score in the adjacent position; computing three dimensional (3D) locations for each of the at least one component; and estimating head pose using the 3D locations.
