  • Tsai, Po-Hsiang; Tran, Tich; Hintz, Thomas; Jan, Tony (IEEE Press, 2008)
    Physiological and/or behavioural characteristics of humans such as face, gait and/or voice have been used in biometric recognition technology. Apart from these characteristics (which have been reported in the literature), ...
  • Tran, Tich; Tsai, Po-Hsiang; Jan, Tony (IEEE, 2008)
    Email is a commonly used tool for communication which allows rapid and asynchronous communication. The growing popularity and low cost of e-mails have made spamming an extremely serious problem today. Several anti-spam ...
  • Tsai, Po-Hsiang; Cao, Longbing; Hintz, Thomas; Jan, Tony (Elsevier Science Bv, 2009)
    Among many biometric characteristics, the facial biometric is considered to be the least intrusive technology that can be deployed in the real-world visual surveillance environment. However, in facial biometric, little ...
  • Tran, Tich; Nguyen, Thi Thanh Sang; Tsai, Po-Hsiang; Kong, Xiaoying (Kluwer Academic Publishers, 2011)
    Detailed information on ACM DL web site: http://dl.acm.org/citation.cfm?id=1969389.1969400 "BSPNN: boosted subspace probabilistic neural network for email security"
  • Tsai, Po-Hsiang; Hintz, Thomas; Tran, Tich; Jan, Tony (IN-TECH, 2008)
    Facial analysis and recognition have received substential attention from researchers in biometrics, pattern recognition, and computer vision communities. They have a large number of applications, such as security, ...
  • Jan, Tony; Tsai, Po-Hsiang; Piccardi, Massimo; Hintz, Thomas (IEEE Press, 2004)
    In multimedia applications such as MPEG-4, an ejicient model is required to encode and classih @ideo objects such as human, car and building. Recently Su,?port Vector Machine (SVM) has been shown to be a good c!assijer: ...
  • Tsai, Po-Hsiang; Tran, Tich; Hintz, Thomas; Jan, Tony (IEEE Press, 2008)
    This paper introduces a framework that employs the Fisher linear discriminant model (FLDM) and classifier (FLDC) on integrated facial appearance and facial expression features. The principal component analysis (PCA) is ...
  • Tsai, Po-Hsiang; Jan, Tony (IEEE Press, 2005)
    Face recognition has been recognized as most simple and non-intrusive technology that can be applied in many places. However, there are still many unsolved face recognition problems such as facial deformations, pose or ...
  • Tsai, Po-Hsiang; Tran, Tich; Cao, Longbing (IEEE, 2009)
    Facial identification has been recognized as most simple and non-intrusive technology that can be applied in many places. However, there are still many unsolved facial identification problems due to different intra-personal ...
  • Tsai, Po-Hsiang; Hintz, Thomas; Jan, Tony (IEEE Press, 2007)
    Physiological and/or behavioral characteristics of humans such as face, gait and/or voice have been used in biometric recognition technology. Apart from those characteristics reported in the literature, the hypothesis of ...
  • Tsai, Po-Hsiang; Jan, Tony; Hintz, Thomas (IEEE Press, 2007)
    In face recognition, if the extracted input data contains misleading information (uncertainty), the classifiers may produce degraded classification performance. In this paper, we employed kernel-based discriminant analysis ...
  • Tran, Tich; Tsai, Po-Hsiang; Jan, Tony; He, Sean (IGI Global, 2010)
    Most of the currently available network security techniques are not able to cope with the dynamic and increasingly complex nature of cyber attacks on distributed computer systems. Therefore, an automated and adaptive ...
  • Jiang, Yunzhi; Tsai, Po-Hsiang; Hao, Zhifeng; Cao, Longbing (IEEE, 2012)
    Segmentation is a process to obtain the desirable features in image processing. However, the existing techniques that use the multilevel thresholding method in image segmentation are computationally demanding due to the ...
  • Tsai, Po-Hsiang; Jan, Tony; Gunes, Hatice (IEEE, 2004)
    Recently, support vector machine (SVM) has been shown to be a good classifier; however, its large computational requirement prohibited its use in real time video processing applications. In this paper, a model is proposed ...
