Shape images generated with different settings for reference. That in Figure 10a is from the initialized face with a zero vector as shape code. That in Figure 10c is from the master face generated using the FMR-based objective function and a larger weight of regularization term (1e-2). That in Figure 10b is from the master face generated using the score-based objective function and a smaller weight of regularization term (1e-3). That in Figure 10d is from the master face with the best 3D FMR, generated using the FMR-based objective function and a smaller weight of regularization term (1e-3).
