PyTorch code for 'Fast and Efficient Facial Expression Recognition Using a Gabor Convolutional Network' (IEEE Signal Processing Letters, Vol. 27:1954-1958, 2020)
Highlights:
(1) This model is very light, only 4 convolutional layers and 2 FC layers (including the FC for softmax loss).
(2) Recognition accuracy (pretrained on AffectNet database): 73.36 at FER2013 (test set), 88.91 at FERPlus (test set), 88.92 at RAF-DB.
(3) Very speed (9.0 s per epoch for training on RAF-DB) and lowest resoure requirments.
Note that:
Requires setup the package for Gabor Convolutional networks https://github.com/jxgu1016/Gabor_CNN_PyTorch
'main_train_test.py' provides training and testing. Hyperparams using the default values.
'test_demo.py' is testing file with trained models (weights) in the directory 'trained_weights'
The directory 'test_demo_without_installing_GCN' is a tesing demo without instaling GCN package
