## Installation
* clone this repo
* git clone https://github.com/open-mmlab/mmdetection.git
* install mmdetection: please follow the guidence in its github
```bash
$ cd mmdetection
$ pip install -r requirements/build.txt
$ pip install "git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI"
$ pip install -v -e . # or "python setup.py develop"
$ pip list | grep mmdet
```
* Download [test set](http://data.csail.mit.edu/tofu/testset/vimeo_interp_test.zip)
```bash
$ unzip vimeo_interp_test.zip
$ cd vimeo_interp_test
$ mkdir sequences
$ cp target/* sequences/ -r
$ cp input/* sequences/ -r
```
* Download BDCN's pre-trained model:bdcn_pretrained_on_bsds500.pth to ./model/bdcn/final-model/
Ps: For your convenience, you can only download the bdcn_pretrained_on_bsds500.pth: [Google Drive](https://drive.google.com/file/d/1Zot0P8pSBawnehTE32T-8J0rjYq6CSAT/view?usp=sharing) or all of the pre-trained bdcn models its authors provided: [Google Drive](https://drive.google.com/file/d/1CmDMypSlLM6EAvOt5yjwUQ7O5w-xCm1n/view). For a Baidu Cloud link, you can resort to BDCN's GitHub repository.
```
$ pip install scikit-image visdom tqdm prefetch-generator
```

Place FeFlow.ckpt to ./checkpoints/.

## Evaluation
```bash
$ CUDA_VISIBLE_DEVICES=0 python eval_Vimeo90K.py --checkpoint ./checkpoints/FeFlow.ckpt --dataset_root ~/datasets/videos/vimeo_interp_test --visdom_env test --vimeo90k --imgpath ./results/
```
## Test your video
```bash
$ CUDA_VISIBLE_DEVICES=0 python sequence_run.py --checkpoint checkpoints/FeFlow.ckpt --video_path ./yourvideo.mp4 --t_interp 4 --slow_motion
```
`--t_interp` sets frame multiples, only power of 2(2,4,8...) are supported. Use flag `--slow_motion` to slow down the video which maintains the original fps.
The output video will be saved as output.mp4 in your working diractory.
## Training
Training Code **train.py** is available now. I can't run it for comfirmation now because I've left the Lab, but I'm sure it will work with right argument settings.
```bash
$ CUDA_VISIBLE_DEVICES=0,1 python train.py
```
* Please read the **arguments' help** carefully to fully control the **two-step training**.
* Pay attention to the `--GEN_DE` which is the flag to set the model to Stage-I or Stage-II.
* 2 GPUs is necessary for training or the small batch\_size will cause training process crash.
* Deformable CNN is not stable enough so that you may face training crash sometimes(I didn't fix the random seed), but it can be detected soon after the beginning of running by visualizing results using Visdom.
* Visdom visualization codes[line 75, 201-216 and 338-353] are included which is good for viewing training process and checking crash.
