Audio-Visual Event Localization in Unconstrained Videos (To appear in ECCV 2018)

Project ArXiv Demo Video

Watch the video

AVE Dataset & Features

AVE dataset can be downloaded from https://drive.google.com/open?id=1FjKwe79e0u96vdjIVwfRQ1V6SoDHe7kK.

Audio feature and visual feature (7.7GB) are also released. Please put videos of AVE dataset into /data/AVE folder and features into /data folder before running the code.

Scripts for generating audio and visual features: https://drive.google.com/file/d/1TJL3cIpZsPHGVAdMgyr43u_vlsxcghKY/view?usp=sharing (Feel free to modify and use it to precess your audio and visual data).

Requirements

Python-3.6, Pytorch-0.3.0, Keras, ffmpeg.

Visualize attention maps

Run: python attention_visualization.py to generate audio-guided visual attention maps.

Supervised audio-visual event localization

Testing:

A+V-att model in the paper: python supervised_main.py --model_name AV_att

DMRN model in the paper: python supervised_main.py --model_name DMRN

Training:

python supervised_main.py --model_name AV_att --train

Weakly-supervised audio-visual event localization

We add some videos without audio-visual events into training data. Therefore, the labels of these videos are background. Processed visual features can be found in visual_feature_noisy.h5. Put the feature into data folder.

Testing:

W-A+V-att model in the paper: python weak_supervised_main.py

Training:

python weak_supervised_main.py --train

Cross-modality localization

For this task, we developed a cross-modal matching network. Here, we used visual feature vectors via global average pooling, and you can find here. Please put the feature into data folder. Note that the code was implemented via Keras-2.0 with Tensorflow as the backend.

Testing:

python cmm_test.py

Training:

python cmm_train.py

Acknowledgements

Audio features are extracted using vggish and the audio-guided visual attention model was implemented highly based on adaptive attention. We thank the authors for sharing their codes. If you use our codes, please also cite their nice works.
