Abstract A novel framework for
appearance-based photorealistic facial modeling, called Merging Face (M-Face), is presented and applied to generate
emotional facial attributes in rotated views. Assuming that human faces
belong to both the linear object class and the Lambertian
object class, we span the face space and attribute space, respectively, by
using groups of prototypes and merging ratio image (MRI). The MRI is defined
as the seamless blend of individual expression ratio image, aging ratio
image, and illumination ratio image (quotient image). The M-Face integrates
the view space projection, shape caricaturing, and texture MRI-mapping
techniques. Derived from the average face, the caricatured shape is reshaped
to be more distinct by exaggerating individual distinctiveness, while the rerendered texture multiplies the MRI information during
the caricaturing. Based on the M-Face model, the expression morphing,
chronological aging or rejuvenating, and illumination variance can be merged
seamlessly in a photorealistic style on desired view-rotated faces yielded by
view morphing. This framework has the following advantages. First, 3-D
reconstruction is avoided without weakening photorealistic effects. Second,
the integration of shape caricaturing and texture MRI-mapping proves by
experiments to be an efficient and computational inexpensive strategy for
realistic face synthesis. Finally, the M-Face is a 2-D parameter-driven model,
which highly simplifies user manipulations. The potential applications of
M-Face are in various fields like virtual human face, speech-driven talking
head, digital painting, film-making, and low-bit-rate communication. |
