        <br><br>
        
        ## Install
        
        ```bash
        $ pip install cmask2polygons
        ```
        
        <br><br>
        
        ## How to Use
        
        ```python
        from cmask2polygons import get_polygons_per_class
        
        
        color_mask_path = '. . .'
        color_mask = cv2.cvtColor(cv2.imread(color_mask_path), cv2.COLOR_BGR2RGB)
        
        # Key:str, Val:tuple
        cls_color_map = {
            "class_name_1": (125, 125, 125),  # RGB Color
            "class_name_2": (70, 20, 225),
            . . .
        }
        
        # Get Polygons from Color Label Mask
        polygons_per_class = get_polygons_per_class(
            color_mask=color_mask,
            cls_color_map=cls_color_map,
            min_area=100.0,
            epsilon_param=8e-4,
            pt_type=int,
            add_closept=False,
        )
        ```
        
        ### Arguments
        
        - `color_mask`: RGB Image (`numpy.ndarray`)
        - `cls_color_map`: Color Value per Class (`dict`)
        - `min_area`: Minimum area of object (`float`). Default is 100.0
        - `epsilon_param`: Value for polygon approximating (`float`). Default is 8e-4
        - `pt_type`: Data type of points. Default is `int`
        - `add_closept`: Append end point (== start point) for representing closed. Default is `False`
        
        <br><br>
        
        ### Return
        
        - Data type: `dict`
          - Key: Class name (`str`)
          - Value: list of polygon x (`pt_type`), y (`pt_type`) coordinates
