Figure 8

Illustration of how the stitching function works to create simulated faces with disfigurements. The stitching function finds the interpolation functions that follow the gradient of the learned disfigurement (gradient of structural and textural part inside of red boundary line in A) from the boundary of the target face (blue dashed line in C). Sub-figures D-H are simulation results for varying degrees of disfigurement on the target face B. It may be seen that the stitching functions f _s and f _t smoothly connect the learned disfigurements of varying degrees to the target face using the unknown boundary of the ROI of the target face and gradient of the learned disfigurement.
