InsightFace is an open source 2D and 3D deep face analysis toolbox, mainly based on PyTorch and MXNet. InsightFace uses some of the most recent and accurate methods for face detection, face recognition and face alignment. We're particularly interested in it, because it has one of the best implementations for ArcFace, a cutting-edge machine-learning model that detects the similarities of two images. InsightFace with ArcFace received a 99.83% accuracy score on the Labeled Faces in the Wild (LFW) data set. We're experimenting with it in the context of facial deduplication and have seen promising results.
