3D Biometrics Technologies and Systems

Zhang, David; Lu, Guangming

Pages: 19 –33

[Until now, many 3D scanning technologies have been used in 3D biometrics research field, such as structured light technique, time-of-flight method, and multi-view imaging. Each method has its own characteristics, and can be used for some specified 3D biometrics. This chapter gives an overall...

3D Ear Acquisition System

Zhang, David; Lu, Guangming

Pages: 37 –50

[The human ear is a new feature in biometrics that has several merits over the more common face, fingerprint and iris biometrics. Unlike the fingerprint and iris, it can be easily captured from a distance without a fully cooperative subject. Also, unlike a face, the ear has a relatively stable...

Two Significant Characteristics in 3D Ear

Zhang, David; Lu, Guangming

Pages: 51 –68

[This chapter introduces the methods to extract two significant characteristics in 3D ear images: ear-cheek angle and the dissimilarity of the left and right ears of the same person. The ear-cheek angle is defined as the angle between the normal vector of the cheek-plane and the normal vector of...

3D Ear Feature Extraction and Recognition

Zhang, David; Lu, Guangming

Pages: 69 –81

[In this chapter, we first define five different features in 3D ear, including point, line and area as local feature, and angle and distance as global feature. Then we discuss the methods to extract these features. The experimental results are given to illustrate the effectiveness of the...

3D Palmprint Capturing System

Zhang, David; Lu, Guangming

Pages: 85 –104

[Palmprints have been widely studied for personal authentication because they are highly accurate and incur low costs. Most of the previous work has focused on two-dimensional palmprint identification. However, the inner surfaces of palms not contain only texture information, but also shape...

3D Information in Palmprint

Zhang, David; Lu, Guangming

Pages: 105 –133

[Palmprint has been proved to be one of the most unique and stable biometrics characteristics. Almost all the current palmprint recognition techniques capture the two-dimensional image of the palm surface and use it for feature extraction and matching. Although two-dimensional palmprint...

3D Palmprint Classification by Global Features

Zhang, David; Lu, Guangming

Pages: 135 –152

[Three-dimensional palmprint has proved to be a significant biometrics for personal authentication. Three-dimensional palmprints are harder to counterfeit than two-dimensional palmprints and more robust to variations in illumination and serious scrabbling on the palm surface. Previous work on...

Joint Line and Orientation Features in 3D Palmprint

Zhang, David; Lu, Guangming

Pages: 153 –167

[Two dimensional palmprint has been recognized as an effective biometrics identifier in the past decade. Recently, three-dimensional palmprint recognition was proposed to further improve the performance of palmprint systems. This chapter presents a simple yet efficient scheme for...

3D Fingerprint Acquisition Device

Zhang, David; Lu, Guangming

Pages: 171 –194

[Touchless multi-view fingerprint technique provides a solution to capture 2D fingerprint image with larger effective area and 3D fingerprint image. This chapter thus presents a touchless multi-view 3D fingerprint capture system that acquires three different views of fingerprint images at the...
