First comparison experiments by different datasets were done to estimate the subsidence pattern of China Beijing-Tianjin Intercity Railway roadbed in Tianjin area in this paper. The multi-baseline differential synthetic aperture radar interferometry technique was used to give the subsidence monitoring. During the period of middle 2008 to middle 2009, the experiment results show that the roadbed is...
The technology of motion detection and target contour extraction used in the system of monitor are studied. First, the frequently-used algorithms for motion detection are studied, including frame difference method and background subtraction method, and an algorithm composing of those methods for motion detection is proposed. The principle using traditional snake model to extract contour is analyzed...
