100% Python3 reimplementation of RetinaFace, a solid single-shot face localisation framework in CVPR 2020.
- Replaced CUDA based anchor generator functions with NumPy APIs.
- Stored runtime anchors via dict to avoid duplicate counting.
- Optimized NMS algorithm through vector calculation methods.
- Reduced FPN layers and anchor density for middle-close range detection.
- Used low-level Mxnet APIs to speed up the inference process.
