Aerial Video Surveillance and Exploitation
There is growing interest in performing aerial surveillance using video cameras. Compared to traditional framing cameras, videos provide the capability to observe ongoing activity within a scene and to automatically control the camera to track the activity. However, the high data rates and relatively small field of view of videos present new technical challenges that must be overcome before vid...
متن کاملA Framework for Aerial Video Stabilization
Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them. Aerial surveillance is now a day’s very popular for broadcasting, news, shooting or gathering data from air and providing large quantity of video data for many purposes, including search and rescue, military operati...
متن کاملVideo Surveillance Middleware for Distributed Video Surveillance
protecting major facilities from terrorism and other threats. At the hardware level, standard IP networking devices and IP video cameras enable building thousand-camera networks at a reasonable cost. However, monitoring surveillance networks through human inspection is expensive and remarkably ineffective. Trained operators lose concentration and miss a high percentage of significant events aft...
متن کاملReal-Time Video Stabilization for Unmanned Aerial Vehicles
This paper presents a new real-time video stabilization method for Unmanned Aerial Vehicles (UAV). It mainly consists of three steps. Firstly, the keypoints are located based on FAST corner detection and preliminarily matched. Secondly, the matched keypoints are then involved for estimation of affine transform to reduce false matching keypoints. Finally, motion estimation is performed based on ...
متن کاملAutomatic Association of Chats and Video Tracks for Activity Learning and Recognition in Aerial Video Surveillance
We describe two advanced video analysis techniques, including video-indexed by voice annotations (VIVA) and multi-media indexing and explorer (MINER). VIVA utilizes analyst call-outs (ACOs) in the form of chat messages (voice-to-text) to associate labels with video target tracks, to designate spatial-temporal activity boundaries and to augment video tracking in challenging scenarios. Challengin...
