Unmanned Aerial Vehicle has a high complexity and nonlinear control system, the sensor is the important device to provide flight data for system, so it's performance is the major determinant of Unmanned Aerial Vehicle. The sensor generally damaged suddenly and lack of many fault data samples. So specific to this reason, this paper uses wavelet packet to extract fault energy feature, and designs a...
Crowd understanding has drawn increasing attention from the computer vision community, and its progress is driven by the availability of public crowd datasets. In this paper, we contribute a large-scale benchmark dataset collected from the Shanghai 2010 World Expo. It includes $2630$ annotated video sequences captured by $245$ surveillance cameras, far larger than any public dataset. It covers a large...
In the past decades, technical developments have enabled the delivery of sophisticated mobile spatial audio signals to consumers, over links that range very widely in quality, requiring decisions to be made about the tradeoffs between different aspects of audio quality. It is therefore important to determine the most important spatial quality attributes of reproduced sound fields and to find ways...
