To solve the problem of imaging difference and too few training samples in infrared-visible images matching
a matching network based on intra-class transfer learning is proposed. The network consists of feature extraction subnetwork and metric subnetwork. Owing to four convolutional neural network(CNN)branches in feature extraction subnetwork
the proposed network is referred to as PairsNet for short. The CNN branches extract infrared and visible image features. The visible image is used as the source domain and the infrared image as the target domain. By reducing the maximum mean discrepancy distance of intra-class samples in the two domains
more accurate sample distribution alignment is achieved in the intra-class feature space. The metric subnetwork uses two full connection layers and one softmax layer in series to evaluate infrared-visible image matching performance. Infrared and visible image data sets are built for end-to-end training and testing. The experimental results show
