DCFNet_pytorch_(arXiv)

This repository contains a Python reimplementation of the DCFNet.

Why implementation in python (PyTorch)?

• Magical Autograd mechanism via PyTorch. Do not need to know the complicated BP.
• Fast Fourier Transforms (FFT) supported by PyTorch 0.4.0.
• Engineering demand.
• Fast test speed (120 FPS on GTX 1060) and Multi-GPUs training.

Requirements

git clone --depth=1 https://github.com/foolwood/DCFNet_pytorch

Requirements for PyTorch 0.4.0 and opencv-python

conda install pytorch torchvision -c pytorch
conda install -c menpo opencv

Training data (VID) and Test dataset (OTB).

Test

cd DCFNet_pytorch/track 
ln -s /path/to/your/OTB2015 ./dataset/OTB2015
ln -s ./dataset/OTB2015 ./dataset/OTB2013
cd dataset & python gen_otb2013.py
python DCFNet.py

Train

1. Download training data. (ILSVRC2015 VID)

   ./ILSVRC2015
   ├── Annotations
   │   └── VID├── a -> ./ILSVRC2015_VID_train_0000
   │          ├── b -> ./ILSVRC2015_VID_train_0001
   │          ├── c -> ./ILSVRC2015_VID_train_0002
   │          ├── d -> ./ILSVRC2015_VID_train_0003
   │          ├── e -> ./val
   │          ├── ILSVRC2015_VID_train_0000
   │          ├── ILSVRC2015_VID_train_0001
   │          ├── ILSVRC2015_VID_train_0002
   │          ├── ILSVRC2015_VID_train_0003
   │          └── val
   ├── Data
   │   └── VID...........same as Annotations
   └── ImageSets
       └── VID
   

2. Prepare training data for dataloader.

   cd DCFNet_pytorch/train/dataset
   python parse_vid.py <VID_path>  # save all vid info in a single json
   python gen_snippet.py  # generate snippets
   python crop_image.py  # crop and generate a json for dataloader

3. Training. (on multiple GPUs ⚡ ⚡ ⚡ ⚡)

   cd DCFNet_pytorch/train/
   CUDA_VISIBLE_DEVICES=0,1,2,3 python train_DCFNet.py
   

Fine-tune hyper-parameter

1. After training, you can simple test the model with default parameter.

   cd DCFNet_pytorch/track/
   python DCFNet --model ../train/work/crop_125_2.0/checkpoint.pth.tar

2. Search a better hyper-parameter.

   CUDA_VISIBLE_DEVICES=0 python tune_otb.py  # run on parallel to speed up searching
   python eval_otb.py OTB2013 * 0 10000
