Abstract
A face tracking system generates a model for extracting a set of facial anchor points on a face within a portion of a face image based a multiple-level cascade of decision trees. The face tracking system identifies a mesh shape adjusted to an image of a face. For each decision tree, the face tracking system identifies an adjustment vector for the mesh shape relative to the image of the face. For each cascade level, the face tracking system combines the identified adjustment for each decision tree to determine a combined adjustment vector for the cascade level. The face tracking system modifies adjustment of the mesh shape to the face in the image based on the combined adjustment vector. The face tracking system reduces the model to a dictionary and atom weights using a learned dictionary. The model may be more easily transmitted to devices and stored on devices.
