METHOD AND SYSTEM FOR SYNTHESIS OF NON-PRIMARY FACIAL EXPRESSIONS

摘要

The present invention relates to a method for synthesis of a non-primary facial expression. The method comprises acquiring a facial image and calculating a shape and a texture for each of a plurality of primary facial expressions for the facial image. The method further comprises the step of generating a subject-specific model of the face including each of the primary facial expressions using the calculated shapes and textures. The method also comprises selecting an expression vector corresponding to a non-primary facial expression to be synthesised and applying the expression vector to the model to synthesise a facial image having the selected non-primary facial expression. The invention also relates to a system for synthesis of a non-primary facial expression and to a method for generating an expression look-up table.
