Techniques to auto-generate professional background music for the home-made video become highly demanded recently with the prevalence of digital video recorders and social media communities. An automated system far such purpose can significantly relieve users' burden of editing background music to accompany home-made video. However, the major obstacle lies in the fact that the assessment of the video-audio matching quality itself is always subjective. We therefore seek solutions from the rich online sharing professional videos to alleviate this difficulty. Mote specifically, a learning-from-Internet framework is proposed to uncover the underlying structures and rules of the video and audio track association patterns from professional online videos. After collecting a large corpus of online professional videos, a joint probabilistic framework is proposed to model prior knowledge from two aspects, namely, the correlation between video and audio tracks, as well as the transition mode from speech and music components. For novel pure-video input, candidate background music tracks are first selected according to the learnt joint probability model, which are further integrated into a smoothed matching sequence via dynamic programming. Qualitative experiments and comprehensive user studies well demonstrate the effectiveness of the proposed framework for background music auto-generation. Copyright 2010 ACM.

In this paper, we propose space-efficient layout method to show abundant photo set which includes redundant and low quality photos. Since digital camera takes no additional cost to take more photos and even multiple cameras are usually used at the same event, the number of photos also increases. They contain many identical photos which preventing user to catch contents of entire photos at a glance. To set suitable position of photos, we relocate photos from a photo set derived from clustering method or raw photo sequence from cameras. Near identical photos are overlapped to save display space and perceptive arrangement is conducted for users. Temporal interval and spatial relevance between photos determine horizontal distance on layout. Also, a vertical location of photo can be used to represent quality of the photo. Our method can help user to grasp the immanent meaning of the photo contents, easily. It saves window space and enhances browsing and readability of photos.
