Abstract:

In recent years, the global epidemic promotes the further development of Biometrics. As the second generation of biometric technology, finger vein recognition has been applied in various fields due to its high safety and other advantages. As an important part of the finger vein recognition system, the Region of Interest（ROI） extraction is the guarantee of the recognition system performance and the adaptability to different application scenarios. Firstly, finger vein recognition products for commercial use and finger vein acquisition equipment for scientific research are introduced. Secondly, public datasets are collated and analyzed. Moreover, focusing on the main work of ROI extraction in the preprocessing of finger vein images, each step of extraction is discussed, and the representative methods are deeply searched and analyzed. Thirdly, finger vein feature extraction and matching are introduced. Finally, the development and application of ROI extraction in the future are summarized and prospected.
