spectral palm print data (420nm~1100nm). Our experiments showed that 2 spectral bands at 700nm and 960nm could provide<br />
most discriminate information of palm print. This finding could be used as the guidance for designing multispectral palm<br />
print systems in the future.<br />

Automatic Gender Recognition using Fusion of Facial Strips<br />

We propose a fully automatic system that detects and normalizes faces in images and recognizes their genders. To boost the<br />
recognition accuracy, we correct the in-plane and out-of-plane rotations of faces, and align faces based on estimated eye positions.<br />
To perform gender recognition, a face is first decomposed into several horizontal and vertical strips. Then, a regression<br />
function for each strip gives an estimation of the likelihood the strip sample belongs to a specific gender. The likelihoods<br />
from all strips are concatenated to form a new feature, based on which a gender classifier gives the final decision. The proposed<br />
approach achieved an accuracy of 88.1% in recognizing genders of faces in images collected from the World-Wide<br />
Web. For faces in the FERET dataset, our system achieved an accuracy of 98.8%, outperforming all the six state-of-the-art<br />
algorithms compared in this paper<br />

Benchmarking Local Orientation Extraction in Fingerprint Recognition<br />

The computation of local orientations is a fundamental step in fingerprint recognition. Although a large number of approaches<br />
have been proposed in the literature, no systematic quantitative evaluations have been done yet, mainly due to the lack of<br />
proper datasets with associated ground truth information. In this paper we propose a new benchmark (which includes two<br />
datasets and an accuracy metric) and report preliminary results obtained by testing four well-known local orientation extraction<br />
algorithms.<br />

Efficient Finger Vein Localization and Recognition<br />
Li, Xu, Civil Aviation Univ. of China<br />
Yang, Jinfeng, Civil Aviation Univ. of China<br />
In order to achieve accurate recognition of human finger vein (FV), this paper addresses the problems of finger vein localization<br />
and vein feature extraction. An inherent physical property of human fingers is used to localize the region of interest<br />
(ROI) of vein images as well as removing uninformative vein imagery based on the inter-phalangeal joint prior. In addition,<br />
vein images are characterized as a series of energy features through steerable filters. Experimental results show the promising<br />
performance of the proposed algorithm for human vein identification.<br />

Learning the Relationship between High and Low Resolution Images in Kernel Space for Face Super Resolution<br />
Zou, Wilman, W W, Hong Kong Baptist Univ.<br />
Yuen, Pong C, Hong Kong Baptist Univ.<br />
This paper proposes a new nonlinear face super resolution algorithm to address an important issue in face recognition from<br />
surveillance video namely, recognition of low resolution face image with nonlinear variations. The proposed method learns<br />
the nonlinear relationship between low resolution face image and high resolution face image in (nonlinear) kernel feature<br />
space. Moreover, the discriminative term can be easily included in the proposed framework. Experimental results on CMU-<br />
PIE and FRGC v2.0 databases show that proposed method outperforms existing methods as well as the recognition based on<br />
high resolution images.<br />
