# Dependencies
1. Python 3.7.0
The app may work with other versions, but this is the version that was used during development.
# Installation
1. Create a new directory, for example `chromakey`, and place `app.py` inside it.
2. Open the directory in your terminal:
```
cd chromakey
```
3. Create a virtual environment:
```
python -m venv opencv-env
```
4. Activate the environment:
```
.\opencv-env\Scripts\activate
```
5. Install required packages:
```
pip install opencv-contrib-python matplotlib
```
# Usage
1. Run the app using the following syntax:
```
python app.py img_filename bk_filename ofilename
```
Where:
- `img_filename` - path to an image with a green screen.
- `bk_filename` - path to the background image.
- `ofilename` - path to save the edited image. If none is provided, it will be displayed instead.
