face-recognition-resnet100-arcface-onnx

Use Case and High-Level Description

The face-recognition-resnet100-arcface-onnx model is a deep face recognition model with ResNet100 backbone and ArcFace loss. ArcFace is a novel supervisor signal called additive angular margin which used as an additive term in the softmax loss to enhance the discriminative power of softmax loss. This model is pre-trained in MXNet* framework and converted to ONNX* format. More details provided in the paper and repository.
