Figure 6.28 Simulation of a two-view acquisition, computation of the three-

dimensional model, unwrapping, and computation of touch-equivalent images:

(a) simulated acquisition obtained by camera A and (b) by camera B; (c) a

touch-equivalent image computed from the synthetic model after reconstruct-

ing the three-dimensional model from the simulated two-view acquisition and the

unwrapping step; and (d) extraction of the minutiae from the touch-equivalent

image. These results indicate that the synthetic samples obtained using the

proposed method can be effectively used to evaluate biometric recognition ...
