    3D face recognition in the presence of 3D model degradations
    (BIOSIG 2011 – Proceedings of the Biometrics Special Interest Group, 2011) Lemaire, Pierre; Huang, Di; Colineau, Joseph; Ardabilian, Mohsen; Chen, Liming
    The problem of 3D face recognition has received a growing interest in the past decades. While proposed approaches have proven their efficiency over renowned databases as FRGC, little work has been conducted on the robustness of such algorithm to the quality of 3D models. In this work, we present a study of the robustness of our 3D face recognition algorithm, namely MS-ELBP+SIFT, to face model degradations. Those degradations include Gaussian noise, decimation, and holes. Degradations are generated on a subset of the FRGC database, hence enabling us to compare the robustness of our approach to them. Results are provided through a comparative study with the baseline ICP method.

    Increasing the distinctiveness of hand vein images by oriented gradient maps
    (BIOSIG 2011 – Proceedings of the Biometrics Special Interest Group, 2011) Chen, Liming; Huang, Di; Chiheb, Hmida; Amar, Chokri Ben
    Hand vein pattern as a biometric trait for people identification has attracted an increasing interest in the recent years thanks to its properties of uniqueness, permanence, non-invasiveness and strong immunity to forgery. In this paper, we propose to make use of Oriented Gradient Maps (OGMs), that we previously proposed for face recognition using the term of Perceived Facial Images (PFIs), to represent Near-Infrared (NIR) hand dorsa vein images and to highlight the distinctiveness of hand vein patterns. Using a holistic approach through both the popular PCA and LDA, we benchmarked the proposed hand vein representations on the NCUT dataset of 2040 hand vein images and demonstrated the effectiveness of the proposed hand vein representations.
