摘要：
In this paper, the key-frame extraction for video clips which are captured by smart phones are investigated. Different from existing work which exploits the image contents, this work utilizes the sensors embedded in the smart phone, such as accelerometers and the touch screen surface, to infer the user's intention. Those intentions are further analyzed to extract the meaningful video key-frames. The proposed method is not only fast enough for on-device implementation, but it also can improve the key-frame extraction performance. Finally, a prototype is developed in a smart phone and extensive experimental validations are provided to show the advantages of the proposed method.
