MobileFaceNet_Tutorial_Pytorch

• This repo illustrates how to implement MobileFaceNet and Arcface for face recognition task.
• Pretrained model is posted for tests over picture, video and cam
• Help document on how to implement MTCNN+MobileFaceNet is available
• Scripts on transforming MXNET data records in Insightface to images are provided
• Scripts on train and evaluation of MobileFaceNet model are provided

MobileFaceNet Video Demo

Test over Picture, Video and Cam

1. Test Picture

python MTCNN_MobileFaceNet.py -img {image_path}

2. Take Picture for Face Database

• over cam

  python take_picture.py -n {name}
  

• over photo

  python take_ID.py -i {image_path} -n {name}
  

3. Test Video

• over cam

  python cam_demo.py
  

• over video file

  python video_demo.py
  

4. Instruction

MobileFaceNet_Step_by_Step.ipynb

Train

Download training and evaluation data from Model Zoo. All training data has been cropped, aligned and resized as 112 x 112. Put images and annotation files into "data_set" folder. The structure should be arranged as follows:

data_set/
            ---> AgeDB-30
            ---> CASIA_Webface_Image
            ---> CFP-FP
            ---> faces_emore_images
            ---> LFW

1. The following script is provided to convert .bin and .rec file to images:

python data_set/load_images_from_bin.py

2. Generate the corresponding annotation files

python data_set/anno_generation.py

3. Train MobileFaceNet

python Train.py

4. Instruction

MobileFaceNet_Training_Step_by_Step.ipynb

The training results over faces_emore data (5822653 images / 85742 ids) are shown below:

Evaluation

python Evaluation.py

Here is the evaluation result. 'Flip' the image could be applied to encode the embedding feature vector with ~ 0.07% higer accuracy. L2 distance score slightly outperforms cos similarity (not necessarily the same trend for other cases, but it is what we conclude in this work)
