## MODNet - Custom Portrait Video Matting Demo
|
|
This is a MODNet portrait video matting demo that allows you to process custom videos.
|
|
|
|
### 1. Requirements
|
|
The basic requirements for this demo are:
|
|
- Ubuntu System
|
|
- Python 3+
|
|
|
|
|
|
### 2. Introduction
|
|
We use ~400 unlabeled video clips (divided into ~50,000 frames) downloaded from the internet to perform SOC to adapt MODNet to the video domain. **Nonetheless, due to insufficient labeled training data (~3k labeled foregrounds), our model may still make errors in portrait semantics estimation under challenging scenes.** Besides, this demo does not currently support the OFD trick.
|
|
|
|
|
|
For a better experience, please make sure your videos satisfy:
|
|
|
|
* the portrait and background are distinguishable, <i>i.e.</i>, are not similar
|
|
* captured in soft and bright ambient lighting
|
|
* the contents do not move too fast
|
|
|
|
### 3. Run Demo
|
|
We recommend creating a new conda virtual environment to run this demo, as follow:
|
|
|
|
1. Clone the MODNet repository:
|
|
```
|
|
git clone https://github.com/ZHKKKe/MODNet.git
|
|
cd MODNet
|
|
```
|
|
|
|
2. Download the pre-trained model from this [link](https://drive.google.com/file/d/1Nf1ZxeJZJL8Qx9KadcYYyEmmlKhTADxX/view?usp=sharing) and put it into the folder `MODNet/pretrained/`.
|
|
|
|
|
|
3. Create a conda virtual environment named `modnet` (if it doesn't exist) and activate it. Here we use `python=3.6` as an example:
|
|
```
|
|
conda create -n modnet python=3.6
|
|
source activate modnet
|
|
```
|
|
|
|
4. Install the required python dependencies (please make sure your CUDA version is supported by the PyTorch version installed):
|
|
```
|
|
pip install -r demo/video_matting/custom/requirements.txt
|
|
```
|
|
|
|
5. Execute the main code:
|
|
```
|
|
python -m demo.video_matting.custom.run --video YOUR_VIDEO_PATH
|
|
```
|
|
where `YOUR_VIDEO_PATH` is the specific path of your video.
|
|
There are some optional arguments:
|
|
- `--result-type (default=fg)` : fg - save the alpha matte; fg - save the foreground
|
|
- `--fps (default=30)` : fps of the result video
