Q.: Affective visualization and retrieval for music video

Abstract—In modern times, music video (MV) has become an important favorite pastime to people because of its conciseness, convenience, and the ability to bring both audio and visual experi-ences to audiences. As the amount of MVs is explosively increasing, it has become an important task to develop new techniques for ef-fective MV analysis, retrieval, and management. By stimulating the human affective response mechanism, affective video content analysis extracts the affective information contained in videos, and, with the affective information, natural, user-friendly, and effective MV access strategies could be developed. In this paper, a novel in-tegrated system (.MV) is proposed for personalized MV affective analysis, visualization, and retrieval. In.MV, we not only perform the personalized MV affective analysis, which is a challenging and insufficiently covered problem in current affective content anal-ysis field, but also propose novel affective visualization to convert the abstract affective states intuitive and friendly to users. Based on the affective analysis and visualization, affective information based MV retrieval is achieved. Both comprehensive experiments and subjective user studies on a large MV dataset demonstrate that our personalized affective analysis is more effective than the pre-vious algorithms. In addition, affective visualization is proved to be more suitable for affective information-based MV retrieval than the commonly used affective state representation strategies.
