Surveillance video for mobile devices [PDF]
Proceedings. IEEE Conference on Advanced Video and Signal Based Surveillance, 2005., 2006 In this paper, we present a video encoding scheme that uses object-based adaptation to deliver surveillance video to mobile devices. The method relies on a set of complementary video adaptation strategies and generates content that matches various appliance and network resources. Prior to encoding, some of the adaptation strategies exploit video object

Capturing People in Surveillance Video [PDF]
2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007 This paper presents reliable techniques for detecting, tracking, and storing keyframes of people in surveillance video. The first component of our system is a novel face detector algorithm, which is based on first learning local adaptive features for each training image, and then using Adaboost learning to select the most general features for detection.
