Hand shape recognition and palm-print recognition using 2D and 3D features
Michal Dvořák, Martin Drahanský · Institution of Engineering and Technology eBooks · 2018
The current state of palm-print and hand-geometry-based biometrics is presented. The most used methods of acquisition, feature extraction and subsequent identification are described as well as the current state of the commercially available solutions based on these technologies. The limitations of 2D biometrics are discussed along with possible approaches to solving them. 3D scanning techniques utilized in biometrics are introduced and described along with their complimentary nature to the 2D methods. The current development in this area is outlined. Novel multimodal method of biometric image acquisition utilizing the line scanner is introduced, with the experimental results from the proof of concept system demonstrating the capability of hand geometry, fingerprint and palm-print features extraction. The future development direction is outlined by introducing a 3D line scanner and justifying its specification with the required task in mid. The palm-print and hand geometry are two technologies that are often being overlooked in favor of alternatives, despite their advantages. With the advance of cheaper sensing technologies and higher available computing power, some of the shortcomings are being overcome. By expanding these systems into 3D, in a fast and affordable way, these biometrics may very well soon gain in popularity.
