## Getting Started

- Clone the repository

### Prerequisites

- opencv

- Python 3.6+

- numpy

```python

pip install -r requirements.txt

```

## Running

### Training 

    ```

    python main.py

    ```

## Usage

### Training

```

usage: main.py [-h] [--image_path IMAGES_PATH]

               [--filter True]

```

```

optional arguments: -h, --help                show this help message and exit

                    --images_path             path to image

                    --filter                  use guided filter or weighted least square filter

```
