Introduction

We propose a multimodal self-supervised learning framework to obtain semantic representations of videos, which benefits the video summarization task.

Specifically, the self-supervised learning is conducted by exploring the semantic consistency between the videos and text in both coarse-grained and fine-grained fashions, as well as recovering masked frames in the videos.

The multimodal framework is trained on a newly-collected dataset that consists of video-text pairs.

Additionally, we introduce a progressive video summarization method, where the important content in a video is pinpointed progressively to generate better summaries.

Requirements and Dependencies

• python=3.8.13
• pytorch=1.12, ortools=9.3.10497
• pytorch-lightning=1.6.5
• pytorch-transformers=1.2.0

Self-supervised Pretraining

Download the pretrained model to the root dictionary.

OR

Follow the following steps to train the self-supervised model.

Data Preparation

Download the visual features and text information embeddings of the YTVT dataset and uncompress them to ssl/features/ and ssl/info_embed/, respectively.

Self-supervised Pretraining

Run the following command in ssl/ to train the self-supervised model:

$ CUDA_VISIBLE_DEVICES=0,1 python main_ssl.py --config ssl.yaml

The trained model is saved in ssl/results/SSL/checkpoints/.

Progressive Video Summarization

Data Preparation

Download the data and uncompress it to data/.

Training and Evaluation of Video Summarization

Run the following command in the root dictionary to train the video summarization model:

$ sh main.sh CFG_FILE

where CFG_FILE is a configuration file (*.yaml) for different settings. We provide several configuration files in cfgs/. Here is an example for training the model on SumMe in the augmented setting:

$ sh main.sh cfgs/sm_a.yaml

If you pretrain the model yourself, change resume in CFG_FILE to the model saved in ssl/results/SSL/checkpoints/. The results of video summarization are recoded in records.csv.

Source Data

We provide the original videos and text information of YTVT here. Besides, we also provide the re-collected text information of SumMe and TVSum here.
