how to run a simple test

[21pl]

Hi. Your demo video looks very promising! Can you simply tell me the steps to run the inference on a single clip?
For example I want to run your algorithm on a clip named 'test.mp4' with a first frame tri-map image named 'test_trimap.jpg'. Thanks

Hi @21pl,
We added a demo code. You can run a simple example via
bash scripts/eval_s4_demo.sh 0
To run with this code, you should prepare RGB frames and trimap as in ./demo
In ./demo, you can add new videos such as dove, dog, cat, ... etc.

Hi, @flagshipbowtie
The shell script in scripts/eval_s4.sh is the exactly same as python eval.py --gpu [GPU_id] in python command.

eval.py has four options:
--gpu: indicates the GPU id
--trimap: select the unknown region width in trimap (Please see the VideoMattling108 paper for what each means).
--viz: save additional results (composite results and .mp4)
--demo: run for demo
