Environment

• Windows or Linux
• NVIDIA GPU with compute capability 3.5+
• Python 3.5
• Tensorflow

Data

The original data we used in paper are available from the following websites

• Tour20 dataset: https://vcg.ece.ucr.edu/
• TVSum dataset: https://github.com/yalesong/tvsum

Codes

Testing

We offer a testing example with a pre-trained model in the ./model directory. Download this repository and run the following command:

python nn_test.py

The fast-forward result will be in the ./output directory.

Training

If you want to train the model on your own data, you can find the script for training in nn_train.py. For more details, please refer to our paper.
