The video complex event detection method of matching integration between trajectory and multi-label hypergraphs
With the rapid development of the applications of network
enormous multimedia files are emerging every day. Video data is an integration of text
sound
image and other files. Not only being hierarchical
structural and complex
video data is also rich in semantic information. Therefore
extensive attentions have been drawn to how to process video data quickly
extract the video characteristics accurately
and analyze and understand the semantic content deeply. Semantic event detection and analysis could find video information quickly and accurately for users in the vast ocean of video data. It can be applied to the field of video on demand
intelligent monitoring and video mining as well. However
there are still many limitations
such as low recognition rate for multiple moving objects with different characteristics
low accuracy in semantic event detection
difficulties in detecting semantic event correlations
the lack of consistent standards of event semantic description
and so on. The detection and analysis methods of complex event based on matching integration between trajectory and multi-label hypergraphs are proposed. Trajectory and multi-label hypergraphs are constructed for classifying and recognizing the complex events. By matching the trajectory hypergraph and multi-label hypergraph
mapping relationship between trajectory and multiple semantic labels is built to extract the complex semantic events. The recognition of low-level features to high-level semantic is made possible for video events. Compared with other methods
such as event detection method based on graph and multi-label semi-supervised learning methods based on hypergraph
the proposed method has a higher mean average recall rate and mean average accuracy rate in the detection result of the complex event. we propose a new event detection method that is trajectory and multi-label hypergraphs model in this paper. This model is a widely-used detection and analysis of complex semantic-based events method. In their clustering process
their number of vertices and clusters has been more than other graph methods. But
