Abstract
Techniques are provided for facial image replacement between a reference facial image and a target facial image, of varying pose and illumination, using 3-dimensional morphable face models (3DMMs). A methodology implementing the techniques according to an embodiment includes fitting the reference face and the target face to a first and second 3DMM, respectively. The method further includes generating a texture map based on the fitted 3D reference face and rendering the fitted 3D reference face to a pose of the fitted 3D target face. The rendering is based on parameters of the first 3DMM, parameters of the second 3DMM, and the generated texture map associated with the fitted 3D reference face. The method further includes, determining a region of interest of the target facial image; and blending the rendered 3D reference face onto the region of interest of the target facial image to generate a replaced facial image.
