We have developed a wireless sensor node for monitoring the health conditions of animals, in particular chickens. Each wireless sensor node measures the body temperature and activity of a chicken. Because chickens are farmed for a maximum of two years, the required lifetime of a wireless sensor node without replacing the battery must be two years. To achieve ultra-low power consumption, the sensor...
This paper concerns the problem of video stitching automatically in a multi-camera surveillance system. Previous approaches have used multiple calibrated cameras for large scale surveillance and monitoring. In this work, we formulate video stitching as a multi-image matching and blending problem, and use SURF to find matches of key points between images, employ homography matrix to calculate overlapping...
A method of motion detection and tracking based on multi-camera surveillance system is presented in this paper. First detecting moving blocks by dynamic template, and then check the moving blocks, get the elements of computing movement blocks such as spatial characteristics and histogram then detecting and tracking the moving objects according to characteristics of elements. Experiments show that...
When the system for monitoring communications satellite temporary business has been used in practice, due to the increase of the temporary business and the change of the data transfer require, many new problems has been risen. So monitoring efficiency, system independence, flexibility, commercial use and cost must be considered in system design. According to actual needs the system for monitoring...
Everyone would admit that disaster early warning is more important than later treatment and damage repair. If an effective tsunami early warning system had been in place in the Indian Ocean region on 26 December 2004, thousands of lives would have been saved. The same stark lesson can be drawn from other disasters that have killed tens of thousands of people in the past few years. Effective early...
