NEPVR-based palm vein recognition method and system

The invention discloses a palm vein recognition method and system based on NEPVR, and the method comprises the steps: obtaining a palm vein image, and carrying out the ROI extraction processing, and obtaining a palm vein ROI region; the method comprises the following steps: introducing a normalized attention mechanism module and a cascade attention mechanism module on the basis of an OfficientViT backbone network, and constructing a palm vein recognition model (NEPVR); and based on a palm vein recognition model, performing palm vein recognition processing on the palm vein ROI region to obtain a palm vein recognition result. According to the embodiment of the invention, the image recognition calculation efficiency and the image recognition precision of the palm vein recognition model can be improved by improving the attention of the palm vein recognition model on the important information of the image and reducing the redundancy of the model parameters.
