In recent years, deep learning has been widely applied in the extraction and recognition of vein features due to its excellent performance in computer vision. Usually, vein recognition models based on deep learning learn the mapping between a single input image and its label. This approach barely captures the connections between multiple vein images from different categories. To solve this problem, this study introduces a deep learning-based K-nearest neighbor iterative vein recognition algorithm. First, the algorithm extracts features from palm vein images by using advanced deep learning models. Then, it calculates the distances between an image to be classified and training images by using the K-nearest neighbor algorithm, which determines the K most similar images and their labels. A label propagation matrix and a label matrix are created from these feature vectors. Finally, a graph iteration algorithm is used to predict the classifications. Tests are conducted on palm vein datasets provided by Hong Kong Polytechnic University and Tongji University. Recognition accuracies of 99.67% and 92.72% are obtained for the two datasets, respectively.
