Workflow

Dependency

• CUDA >= 6.0
• OpenCV >= 3.0

Usage

Compile the code

unzip lib_eval.zip // this is for evaluation on datasets
bash build.sh

Test on a single image (the first run takes time to load the GPU)

bash run_img.sh

Video streams (a web camera is required)

bash run_video.sh

CRTREES can achieve 200+fps for 480P video streams on a Titan Xp GPU. Faster speed can be achieved if the GPU version of OpenCV is used.

Benchmark

The superpixel benchmark (https://github.com/davidstutz/superpixel-benchmark) shall be put in the same level directory as this project.

bash bench_superpixels.sh BSDS500

The same results as in the paper can be obtained.
