Abstract:
The goal of point-to-set matching is to match a single image with a set of images from a subject. Within an image set, different images contain various levels of discriminative information and thus should contribute differently to the results. However, the discriminative level is not accessible directly. To this end, we propose a confidence driven network to perform point-to-set matching. The proposed system comprises a feature extraction network (FEN) and a performance prediction network (PPN). Given an input image, the FEN generates a template, while the PPN generates a confidence score which measures the discriminative level of the template. At matching time, the template is used to compute a point-to-point similarity. The similarity scores from different samples in the set are integrated at a score level, weighted by the predicted confidence scores. Extensive multi-probe face recognition experiments on the IJB-A and UHDB-31 datasets demonstrate performance improvements over state of the art algorithms.
