Summarizing long-length videos with GAN-enhanced audio/visual features

In this paper, we propose a novel supervised method for summarizing long-length videos. Many recent works presented successful results in video summarization. However, most videos in those works are short in duration (~5 minutes), and the methods often break down on very long videos (~30 minutes). Moreover, most works only use visual features, while audios provide useful features for the task. Based on these observations, we present a model that exploits both visual and audio features. To handle long videos, our model also refines the extracted features using adversarial networks. To demonstrate our model, we have collected a new dataset of 63 e-sports (~30 minutes) videos, each accompanied by an editorial summary video that is about 10% in length of the original video. Evaluation on this dataset suggests that our method produces quality summaries for very long videos.
