Abstract
Structural modifications to a person's face in a reference image are captured and automatically applied to the person's face in another image. The reference image is processed to compute landmark information on the person's face and apply a mesh to the reference image. When structural modifications are made to the person's face in the reference image, the mesh is modified, and the modified mesh is stored in association with the landmark information. Another image is analyzed to compute landmark information on the person's face in that image and apply a mesh to the image. A transformation matrix is computed using the landmark information from the reference image and current image, and the modified mesh from the reference image is transformed using the transformation matrix. The mesh in the current image is modified using the transformed mesh, thereby applying the structural modification to the person's face in the current image.
