JSON to mask

Reads a json file (.json) with a fixed format and converts this to a grayscale png mask. With:

• White (#FF): as the color of the road

• Black (#00): as the background

Usage: json2mask.py <json_file> <rgb_image>

json_file: path to the json file
rgb_image: path to the rgb image

The script outputs the mask as <image_stem>_mask.png to the same folder as the original image.

Requires OpenCV & NumPy:

pip install opencv-python pip install numpy
