FaceBoxes: A CPU Real-time Face Detector with High Accuracy


By Shifeng Zhang


We propose a novel face detector, named FaceBoxes, with superior performance on both speed and accuracy. Moreover, the speed of FaceBoxes is invariant to the number of faces. You can use the code to train/evaluate the FaceBoxes method for face detection. For more details, please refer to our paper.

FaceBoxes Framework

FaceBoxes Performance

Note: The performance of FDDB is the true positive rate (TPR) at 1000 false postives. The speed is for VGA-resolution images.

Citing FaceBoxes

  1. Installation
  2. Training
  3. Evaluation
  4. Others


  1. Get the code. We will call the cloned directory as $FaceBoxes_ROOT.
git clone
  1. Build the code. Please follow Caffe instruction to install all necessary packages and build it.
cd $FaceBoxes_ROOT
# Modify Makefile.config according to your Caffe installation.
# Make sure to include $FaceBoxes_ROOT/python to your PYTHONPATH.
cp Makefile.config.example Makefile.config
make all -j && make py


  1. Download the WIDER FACE dataset, convert it to VOC format and create the LMDB file. Or you can directly download our created LMDB of WIDER FACE to $FaceBoxes_ROOT/examples/.
# You can modify and if needed.
cd $FaceBoxes_ROOT
  1. Train your model on WIDER FACE.
cd $FaceBoxes_ROOT/models/faceboxes


  1. Download the images of AFW, PASCAL Face and FDDB to $FaceBoxes_ROOT/examples/images/.

  2. If you do not train the model by yourself, you can download our trained model.

  3. Check out test/ on how to detect faces using the FaceBoxes model and how to plot detection results.

  4. Evaluate the trained model via test/ on AFW.

  5. Evaluate the trained model via test/ on PASCAL Face.

  6. Evaluate the trained model via test/ on FDDB.

  7. Download the eval_tool to show the performance.


  1. We reimplement the FaceBoxes with PyTorch as FaceBoxes.PyTorch.

  2. We will release a trained model of the imporved version of FaceBoxes, which jonitly performs face detection and alignment (5 landmarks).

Note: If you can not download the created LMDB, the provided images and the trained model through the above links, you can download them through BaiduYun.
