英文摘要: With the popularization of mobile multimedia terminal and the rapid development of the Internet, how to provide effective video retrieval and content adaptation gradually becomes a hot research topic. This proposal aims to research on the mobile video retrieval and browsing approach. Through semantic understanding for videos with noise tags, we investigate the multiple instances graph model for video annotation. Combined with the context information, we study the video retrieval methods based on graph models. To adjust the frame size and video length simultaneously, we investigate video retargeting based on the subspace theory to overcome the limitation of bandwidth and storage. We plan to perform hierarchical clustering for search results with dual-constraint topic models, and generate the video thumbnails with screen adaptation.
