摘要:
A recognition algorithm for hand vein based on speeded-up robust features(SURF) was proposed. Firstly, the region of interest (ROI) of the hand vein image is obtained through image preprocessing. The local SURF features of test sample and register samples are extracted and matched based on Euclid distance, and then the mismatching pairs are rejected. Finally, the matching rate is calculated as the similarity between registered sample and test sample to realize personal identity recognition. The recognition performance was evaluated in verification mode using TJU hand vein image database, the equal error rate (EER) is 0.07% and average recognition time is 0.153 s. Experimental results show that the proposed algorithm is able to realize hand vein recognition reliably and quickly.
