Contactless hand recognition
نویسندگان
چکیده
Traditional hand geometry-based systems use low-resolution cameras or scanners to capture users’ hand images with the help of peggies or by forcing them to touch a screen. Those systems measure a hand shape to extract its features, like lengths and widths of fingers, and hand contour, for recognition. Unfortunately, traditional techniques face unsolved problems: low discriminability due to low-resolution hand images and bad user acceptability because users worry about hygienic issues when they have to touch screens.

Biometric Identification Using a New Direction in Contactless Palmprint Imaging
For the purpose of biometric applications, we explore in this paper a new approach to characterize palmprint features. In recent years, the contactless system emerges as a new viable option to address hygienic issues and improve the user acceptance. In this paper, we examine the issues related to the contactless imaging and we propose a new approach for palmprint recognition captured in contact...
متن کاملContactless palmprint authentication using circular gabor filter and approximated string matching
More and more research have been developed very recently for automatic hand recognition. This paper proposes a new method for contactless hand authentication in complex images. Our system uses skin color and hand shape information for hand detection process. Next, the palm is extracted and characterized by circular Gabor filter. Finally, the palm features are matched by a new normalized approxi...

In this paper, we describe a nui-based application using a Microsoft Kinect. The system displays a digital representation of a university building, where users can navigate virtually through contactless gestures. Users can step up and couple their hand with a virtual mouse cursor to navigate through the program such that hand movements to the right lead to cursor movements to the right for exam...
متن کاملUnconstrained and Contactless Hand Geometry Biometrics
This paper presents a hand biometric system for contact-less, platform-free scenarios, proposing innovative methods in feature extraction, template creation and template matching. The evaluation of the proposed method considers both the use of three contact-less publicly available hand databases, and the comparison of the performance to two competitive pattern recognition techniques existing in...
