Molecular Genetic Pathology, Second Edition presents up-to-date material containing fundamental information relevant to the clinical practice of molecular genetic pathology.

The past decade has seen a rapid growth in the demand for biometric-based - thentication solutions for a number of applications. With signi?cant advances in biometrictechnologyandanincreaseinthenumberofapplicationsincorporating biometrics, it is essential that we bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions for the development and successful deployment of state-of-the-art biometric systems. The InternationalConference onBiometric Authentication (ICBA 2004)was the ?rst major gathering in the Asia-Paci?c region devoted to facilitating this interaction. We are pleased that this conference attracted a large number of high-quality research papers that will bene?t the international biometrics - search community. After a careful review of 157 submissions, 101 papers were acceptedeitherasoral(35)orposter(66)presentations.Inadditiontothesete- nical presentations, this conference also presented the results and summaries of threebiometric competitions: FingerprintVeri?cationCompetition (FVC 2004), Face Authentication Competition (FAC 2004), and Signature Veri?cation C- petition (SVC 2004).This conference provided a forum for the practitioners to discuss their practical experiences in applying the state-of-the-art biometric technologies which will further stimulate research in biometrics. We aregrateful to Jim L. Wayman, Edwin Rood, Raymond Wong, Jonathon Philips,andFrancisHoforacceptingourinvitationtogivekeynotetalksatICBA 2004. In addition, we would like to express our gratitude to all the contributors, reviewers, program committee and organizing committee members who made this a very successful conference. We also wish to acknowledge the Croucher Foundation, the International Association of Pattern Recognition, IEEE Hong Kong Section, the Hong Kong Polytechnic University, the National Natural S- ence Foundation in China, and Springer-Verlag for sponsoring this conference.

Automatic and reliable authentication of individuals is becoming an essential part of the modern world, for security and convenience in our life, in our work andin society.Biometrics-basedsystems utilize physiologicalorbehavioralch- acteristics of an individual including the face, iris, ?ngerprint, palmprint, hand, voice, signature, or a combination of them, for this task. We are now seeing increasing interest and practical deployment of biometric systems. TheInternationalWorkshoponBiometricRecognitionSystems(IWBRS2005) was held in conjunction with ICCV 2005, providing an interactive forum for leading biometrics researchersand system designers.A biometric authentication competition (BAC) was conducted by the workshopto track the state-of-the-art biometrics technologies. This volume of workshop proceedings includes 32 papers carefully selected from a total of 130 submissions. The papers address the problems in face, iris, ?ngerprint, palmprint, speech, writing and other biometrics, and contribute new ideastoresearchanddevelopmentofreliableandpracticalsolutionsforbiometric authentication.We would like to express our gratitude to all the contributors, reviewers, and ProgramCommittee and OrganizingCommittee members who made this a very successful workshop. We also wish to acknowledge the Institute of Automation, ChineseAcademyofSciences,andSpringerforsponsoringthisworkshop.Special thanks are due to Miao Hong, Xin Yang, Zhuoshi Wei, Yinghao Cai, Zhaofeng He, Cheng Zhong, Shiqi Yu and Xianchao Qiu for their hard work in workshop organization. We hope you could bene?t from the fruitful workshop to improve the perf- mance of your biometric systems.

This book constitutes the refereed proceedings of the International Conference on Biometrics, ICB 2006, held in Hong Kong, China in January 2006. The 104 revised full papers presented were carefully reviewed and selected from 192 submissions. Biometric criteria covered by the papers are assigned to face, fingerprint, iris, speech and signature, biometric fusion and performance evaluation, gait, keystrokes, and others. In addition, the results of the Face Authentication Competition (FAC 2006) are also announced in this volume.
