- Abstract:
-
Multimodal biometric recognition has gained widespread attention in the industry due to its excellent performance and robust reliability. However, traditional multimodal biometric recognition methods usually fuse directly at the feature or matching layer and rarely consider the differences in fusion effects caused by the quality of modal samples. Moreover, research on multimodal biometric recognition methods is restricted by the absence of large-scale publicly available multimodal biometric databases. Therefore, first, a hand multimodal data acquisition device is designed, and a hand multimodal database is created for the validation and evaluation of multimodal biometric recognition methods. Second, a palmprint and palm vein fusion recognition method is proposed based on a modal information evaluation strategy. It uses the category confidence level corresponding to ground truth sample labels to assess the information level of each modal feature. Thus, the model adaptively assigns weights according to the contribution rates of different modes during the identity recognition fusion process. This method outperforms other recognition methods by achieving the highest recognition rate on two public databases and one self-built multimodal biometric database.
