Abstract
A method and system for removing head motion from facial motion capture data. The method includes receiving a set of measured points of a target model, wherein each point is associated with coordinates in a 3D space. The method includes computing an optimal affine transformation function. The computing includes selecting an unprocessed point from the set of measured points. The computing includes selecting two nearby neighboring points of the unprocessed point. The computing includes computing an affine transformation function that minimizes an L2-norm error. The computing includes identifying the optimal affine transformation function from a set of computed affine transformation functions. The method includes displaying an aligned target model and reference model utilizing the optimal affine transformation function. The method includes outputting the optimal affine function to a computer-readable storage medium.
