Abstract

A novel image-level fusion algorithm is proposed for 3D face recognition, which synthesizes an integrate image from both 2D intensity and 3D depth images. Due to the same descriptors in 2D and 3D domain, the image combination not only maintains facial intrinsic details to the utmost extent, but also provides more distinctive features. Also as the result of image recognition, the low efficiency of 3D surface matching is eliminated, and a fast 3D face recognition system is carried out. After the proposed surface preprocessing, an enhanced ULBP descriptor is applied to reduce the feature dimension, and LDA is adopted to extract the optimal discriminative components from the integrate image. Experiments performed on the FRGC v2.0 show that this algorithm practically outperforms the existing state-of-art multimodel recognition algorithm and realizes a real-time face recognition system.
