Approximate Initialization of Camera Sensor Networks [PDF]
, 2007 Camera sensor networks--wireless networks of low-power imaging sensors-have become popular recently for monitoring applications. In this paper, we argue that traditional vision-based techniques for calibrating cameras are not directly suitable for low-power sensors deployed in remote locations.

Line cameras for monitoring and surveillance sensor networks [PDF]
Proceedings of the 15th ACM international conference on Multimedia, 2007 A linear CCD sensor reads temporal data from a CCD array continuously and forms a 2D image profile. Compared to most of the sensors in the current sensor networks that output temporal signals, it delivers more information such as color, shape, and event of a flowing scene.
