Improved ArcFace: Some improvements on ArcFace model
Reference: https://github.com/deepinsight/insightface (Official repository of ArcFace)
Preparation
Create your dataset like the sample dataset:
data
--YourDatasetName
--Label 1
----image1.jpg
----image2.jpg
----...
--Label 2
----...
You can find pretrained model at link
For face alignment, run
python align_face.py --root_dir /path/to/dataset/folder --dst_w 112 --dst_h 112
(You can change the destination size --dst_w
is output width and --dst_h
is output height)
Configuration
Train
loss
: Now you can chooseArcFace
orElasticArcFace
.backbone
: Find supported backbone in ArcFaceModel's docstring.irse50
andmobilefacenet
have pretrained models on insightface's datasets at link. Other ones are listed in the doctring ofArcFaceModel
class, but they have to be trained from scratch.freeze_model
: Freeze the backbone of trained model for transfer learning. Set its value isfalse
to train from scratch.root_dir
: The path to the directory of train datasetuse_lr_scheduler
: Use learning rate scheduler.optimizer
: Optimizer for training progress.sam
,lamb
,adam
andadan
are supported optimizer. You can find the original implementation of SAM, LAMB and Adan. If you don't change the config, the default optimizer is ADAM.verbose
: 0: nothing will be shown; 1: shows results per epoch only; 2: shows train losses per iterationprefix
: Prefix of saved model's name.
Test
trainset_path
: Path to the directory of dataset used for training the test model.testset_path
: Path to the directory of test dataset.pretrained_model_path
: Path to the pretrained model.
Training
In terminal, run
python main.py --config ./path/to/config/file.json --phase train --device [gpu_id]
Currently, only training on a single gpu is supported.
Testing
In terminal, run
python main.py --config ./path/to/config/file.json --phase test --device [gpu_id]
Verification
In terminal, run
python verification.py --config ./path/to/config/file.json
Inference on single image is also supported, check the commented lines in the verification.py
file. Filling hair is a miscellaneous option to observe the decrease of model's performance when the given face is partly covered.
