## README

# DCFNet_pytorch<sub>([arXiv](https://arxiv.org/pdf/1704.04057.pdf))</sub>

This repository contains a Python *reimplementation* of the [**DCFNet**](https://arxiv.org/pdf/1704.04057.pdf).

### 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

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

Requirements for **PyTorch 0.4.0** and opencv-python

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

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

## Test

```shell
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**](http://bvisionweb1.cs.unc.edu/ilsvrc2015/download-videos-3j16.php#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`.

   ```shell
   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*** :zap: :zap: :zap: :zap:)

   ```
   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.

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

2. Search a better hyper-parameter.

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