Eigenspace dimension. 5 Conclusion We present a face recognition algorithm using corresponding range and gray-level facial images. Experiment results have demonstrated the promising performance of our algorithm. For a larger face database, due to the discriminating representation by integrating the shape and texture information and the robustness of the chosen feature in our system, our algorithm will not deteriorate, which will be evaluated in our future work. Furthermore, other classifiers such as Support Vector Machine will be adopted in our system.

The augmented Gabor feature vector introduced in Sect. 2 resides in a space of very high dimensionality, and we first apply PCA for dimensionality reduction: Y (ρ) = P t X (ρ) (4) where P = [P1 P2 · · · Pn ] consists of the n eigenvectors corresponding to the leading eigenvalues of the covariance matrix of X (ρ), n < N and P ∈ RN ×n. The lower dimensional vector Y (ρ) ∈ Rn captures the most expressive features of the original data X (ρ). The PCA output is then processed by the ICA method and its reduced dimension n is determined based upon the ICA sensitivity analysis.
