Evaluate on WIDER FACE val with trained model

export WIDERFACEPATH=/path/to/your/wider/face/dataset
export MODELPATH=/path/to/your/caffemodel/final.caffemodel
CUDA_VISIBLE_DEVICES=0,1,2,3 python train_test.py --train false --conf configs/smallhardface.toml --amend TEST.MODEL $MODELPATH DATA_DIR $WIDERFACEPATH

The result will be stored in $ROOT/output/face/wider_val/face_$TIME where $TIME is the timestamp when the code begins to run. The APs computed by our unofficial python code lib/wider_eval_tools/wider_eval.py can be found at the end of $ROOT/output/face/wider_val/face_$TIME/stderr.log. For APs computed by official MATLAB code, please evaluate $ROOT/output/face/wider_val/face_$TIME/result.tar.gz with official evaluation toolkit.

Evaluate on FDDB with trained model

export FDDBPATH=/path/to/your/fddb/dataset
export MODELPATH=/path/to/your/caffemodel/final.caffemodel
CUDA_VISIBLE_DEVICES=0,1,2,3 python train_test.py --train false --conf configs/smallhardface-fddb.toml --amend TEST.MODEL $MODELPATH DATA_DIR $FDDBPATH

The result will be stored in $ROOT/output/face/fddb_val/face_$TIME where $TIME is the timestamp when the code begins to run. The TPR@1000 can be found at the end of $ROOT/output/face/fddb_val/face_$TIME/stderr.log. To plot TPR curve, copy rect_DiscROC.txt into $ROOT/external/marcopede-face-eval-f2870fd85d48/detections/fddb and run $ROOT/external/marcopede-face-eval-f2870fd85d48/plot_AP_fddb.py.

Evaluate on Pascal Faces with trained model

export PASCALPATH=/path/to/your/pascal/dataset
export MODELPATH=/path/to/your/caffemodel/final.caffemodel
CUDA_VISIBLE_DEVICES=0,1,2,3 python train_test.py --train false --conf configs/smallhardface-pascal.toml --amend TEST.MODEL $MODELPATH DATA_DIR $PASCALPATH

The result will be stored in $ROOT/output/face/pascalface_val/face_$TIME where $TIME is the timestamp when the code begins to run. To plot PR curve, copy pascal_res.txt into $ROOT/external/marcopede-face-eval-f2870fd85d48/detections/PASCAL and run $ROOT/external/marcopede-face-eval-f2870fd85d48/plot_AP.py.

Evaluate on AFW with trained model

export AFWPATH=/path/to/your/afw/dataset
export MODELPATH=/path/to/your/caffemodel/final.caffemodel
CUDA_VISIBLE_DEVICES=0,1,2,3 python train_test.py --train false --conf configs/smallhardface-afw.toml --amend TEST.MODEL $MODELPATH DATA_DIR $AFWPATH

The result will be stored in $ROOT/output/face/afw_val/face_$TIME where $TIME is the timestamp when the code begins to run. To plot PR curve, copy afw_res.txt into $ROOT/external/marcopede-face-eval-f2870fd85d48/detections/AFW and run $ROOT/external/marcopede-face-eval-f2870fd85d48/plot_AP.py.

Train face detector on WIDER FACE train

Link to the ImageNet pre-trained model

export WIDERFACEPATH=/path/to/your/wider/face/dataset
export MODELPATH=/path/to/your/pretrained/model.caffemodel
CUDA_VISIBLE_DEVICES=0,1,2,3 python train_test.py --conf configs/smallhardface.toml --amend DATA_DIR $WIDERFACEPATH TRAIN.PRETRAINED $MODELPATH

The trained model will be stored in $ROOT/output/face/wider_train/face_$TIME where $TIME is the timestamp when the code begins to run.
