+===== Introduction =====
+RetinaFace is a face detection model. It can draw five key points on each face, including two eyes, nose and two corners of mouth.
+Inference results on Edge2.
+{{:products:sbc:edge2:npu:demos:retinaface-result.jpg?800|}}
+**Inference speed test**: USB camera about **39ms** per frame. MIPI camera about **33ms** per frame.
+===== Train Model =====
+The codes we use [[gh>bubbliiiing/retinaface-pytorch]].
 ```shell
 git clone https://github.com/bubbliiiing/retinaface-pytorch
+```

 After training model, we should convert pytorch model to onnx model. Create a python file written as follows and run.
