EasyFace

EasyFace旨在快速选型/了解/对比/体验人脸相关sota模型，依托于Modelscope开发库和Pytorch框架，EasyFace具有以下特性:

  • 快速体验/对比/选型Sota的人脸相关模型, 涉及人脸检测，人脸识别，人脸关键点，人脸表情识别，人脸活体检测等领域，目前支持人脸检测相关sota模型。
  • 5行代码即可进行模型推理，10行代码进行模型训练/Finetune, 20行代码对比不同模型在自建/公开数据集上的精度以及可视化结果。
  • 基于现有模型快速搭建创空间应用。

News 📢

🔥 2023-03-10：新增DamoFD（ICLR23）人脸检测关键点模型，基于SCRFD框架进一步搜索了FD-friendly backbone结构。 在0.5/2.5/10/34 GFlops VGA分辨率的算力约束条件下性能均超过SCRFD。其中提出的轻量级的检测器DDSAR-0.5G在VGA分辨率0.5GFlops条件下WiderFace上hard集精度为71.03(超过SCRFD 2.5个点)，欢迎大家一键使用(支持训练和推理)，paper。

🔥 2023-03-10：新增4个人脸检测模型，包括DamoFD，MogFace，RetinaFace，Mtcnn。
