Classification: CPC G | IPC G

Claim 6:
7. A non-transitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to perform a series of operations comprising:
identifying a body surface portrayed in a reference image of a physical subject based on respective body surface marker points in the reference image;
generating a representation of the body surface by reference to a group of known body surface positions that correspond with one or more facial muscles associated with a predetermined facial expression, the representation generated by applying a weight to at least one of the known body surface positions and further by utilization of L1-norm regularization via a physiological based energy equation;
retargeting of the representation of the body surface determined according to selection of a plurality of shape primitives; and
based on the retargeting, performing the predetermined facial expression due to a result of evaluating the plurality of shape primitives according to an energy minimization function reaching a required minimum activation energy threshold of the predetermined facial expression.
