output

usage

Automatically downloads the onnx and prototxt files on the first run. It is necessary to be connected to the Internet while downloading.

For the sample image,

$ python3 deep-image-matting.py

If you want to specify the input image, put the image path after the --input and --trimap option.
You can use --savepath option to change the name of the output file to save.

$ python3 deep-image-matting.py --input IMAGE_PATH --trimap TRIMAP_PATH --savepath SAVE_IMAGE_PATH

By adding the --video option, you can input the video.
If you pass 0 as an argument to VIDEO_PATH, you can use the webcam input instead of the video file. The trimap is generated by DeeplabV3.

$ python3 deep-image-matting.py --video VIDEO_PATH
