摘要：A method for image alignment is disclosed. In one embodiment, the methodincludes acquiring a facial image of a person and using a discriminative face alignment
model to fit a generic facial mesh to the facial image to facilitate locating of facialfeatures. The discriminative face alignment model may include a generative shape modelcomponent and a discriminative appearance model component. Further, the
discriminative appearance model component may have been trained to estimate a scorefunction that minimizes the angle between a gradient direction and a vector pointingtoward a ground-truth shape parameter. Additional methods, systems, and articles ofmanufacture are also disclosed.
