This paper presents a novel mesh deformation method for transferring reference facial blendshapes to a source face model. The presented method uses information provided by a source and a reference face model to analyze the mesh similarities and, consequently, to transfer the deformation. This is achieved by considering the distribution of vertices between the two face models in conjunction with the gradients of the meshes. Both of these components are assigned to an optimization function that is solved in two steps: (i) distribution transfer and (ii) gradient maintenance optimization. Finally, in order to analyze the efficiency of such a method, the presented method was evaluated against previous solutions in terms of deformation transfer error, and computational time.
