Introduction

MindFace mainly has the following features.

• Unified Application Programming Interface

  MindFace provides a unified application programming interface for face recognition and detection by decoupling the models, so that the model can be called directly using the MindFace APIs, which greatly improves the ease of building algorithms for users

• Strong extensibility

  MindFace currently supports face recognition and detection, based on the unified APIs. MindFace is highly scalable, it can support lots of backbones, datasets, and loss functions. What's more, MindFace also supports many platforms, including CPU/GPU/Ascend.

Benchmark Results

Recognition

The MindSpore implementation of ArcFace and has achieved great performance. We implemented three versions based on ResNet and MobileNet to meet different needs. Detailed results are shown in the table below.
