Biometric is a technology for verification or identification of individuals by employing a
person's physiological and behavioural traits. Although these systems are more secured …

We propose the use of correlation mapping optical coherence tomography (cmOCT) to
deliver additional biometrics associated with the finger that could complement existing …

Face recognition in an unconstrained environment is still a challenging problem. Variations
in aging, partially visible faces, expression, illumination, pose, disguise, and twin faces are …

Emotional state recognition is an important component for efficient human–computer
interaction. Most existing works address this problem using 2D features, which are usually …

The increasing availability of 3D facial data offers the potential to overcome the difficulties
inherent with 2D face recognition, including the sensitivity to illumination conditions and …

The majority of the authentication systems found today can be broken or stolen and
generally are characterized by reduced security. Therefore, numerous efforts have been …

在指纹识别模块中采用改进的OPTA 算法对指纹图像进行二值化和细化, 采用基于Hough
变换点模式匹配算法对特征图像进行匹配; 在人脸识别模块中, 采用基于二维Gabor …

The main contributions of this paper are proposing a robust matching measure that employs
multiple images of a subject to enroll an iris and that can be used with both types of feature …

Traditional 2D face recognition based on optical (intensity or color) images faces many
challenges, such as illumination, expression, and pose variation. In fact, the human face …

One of the challenges in pattern recognition technologies, especially face recognition, is the
ability to handle scenarios where subjects are non-cooperative in terms of position (face …
