MAC OS X or Linux
NVIDIA GPU with compute capability 3.5+
Python 2.7+
Theano 0.7+
Matlab

Data

Download the data and unzip to ./data/

Note that we down-sampled the original video by 2fps.

file name: in the format 'Data_$Dataset$_google_p5.h5', e.g. Data_SumMe_google_p5.h5, means the frame level feature of SumMe dataset.
the index of videos are stored as ‘idx’ in the file, in most cases it’s from 1 to n, where n is the number of videos in the dataset (except for Youtube dataset).
feature & ground-truth: the feature is indexed as ‘fea_i’ , the importance is indexed as ‘gt_1_i’ (real number, from the original dataset), and the keyframe we used is indexed as ‘gt_2_i’ (binary value transferred from the original dataset) for the i-th video in the dataset.

Original videos and annotations for each dataset are also available from the the authors' project page

TVSum dataset: https://github.com/yalesong/tvsum
SumMe dataset: https://people.ee.ethz.ch/~gyglim/vsum/#benchmark

Codes

dppLSTM for video summarization

We have enclosed pre-trained models in the ./model directory download the model and run the following commands:

Download the pre-trained models and unzip it to ./models and run the following commands:

cd ./codes
THEANO_FLAGS=device=gpu0,floatX=float32 python dppLSTM_main.py

This will automatically run summarization on the video data using pre-trained model, and save the results in ./res_LSTM/ as dppLSTM_$DATASET$_2_inference.h5

If you want to train the model on your own data, just uncomment Line 85 in dppLSTM_main.py

train(model_idx = model_idx, train_set = train_set, val_set = val_set, model_saved = model_file)

Evaluation

For both SumMe and TVSum datasets, you can find the code for evaluation provided by the author:

TVSum: https://github.com/yalesong/tvsum
SumMe: https://people.ee.ethz.ch/~gyglim/vsum/#benchmark

We also provided the evaluation code with wrappers that help adapt to the datasets above

To run evaluation on the predicted summarization, start the matlab and run the following commands:

cd ./codes
dppLSTM_eval('../data/', '$DATASET$', '/dppLSTM_$DATASET$_2_inference.h5')
