Emotion Expression With Fact Transfer for Video Description

Translating a video into natural language is a fundamental but challenging task in visual understanding, since there is a great gap between visual content and linguistic sentence. More attention has been paid to this research field and a number of state-of-the-art results are achieved in recent years. However, the emotions in videos are usually overlooked, leading to the generated description sentences being boring and colorless. In this work, we construct a new dataset for video description with emotion expression, which consists of two parts: a re-annotated subset of the MSVD dataset with emotion embedded and another subset annotated with long sentences and rich emotions based on a video emotion recognition dataset. A fact transfer based framework is designed, which incorporates a fact stream and an emotion stream to generate sentences with emotion expression for video description. In addition, we propose a novel approach for sentence evaluation by balancing facts and emotions. A group of experiments are conducted, and the experimental results demonstrate the effectiveness of the proposed methods, including the idea of dataset construction for video description with emotion expression, model training and testing, and the emotion evaluation metric.
