Deformable Objects' Contour Extraction

Zhou Yanbo;Zhang Zhiguang(BME Group, Dept.of Electrical Engineering, Tsinghua University,Beijing100084)  
Edge information is regeded as important chalacteristics in computer vision. Thus, edge detection and contour extraction are key steps of image analysis. For edge detection, research intersts was tuned to local enemy method based on local phase in recent years. It's main feature is that we can obtain many types of edges simultaneously by detecting the maximum value of local energy. After that, we get the inihal edge. In order to obtain the objects' contour, the snakes madal presented by M. Kass in 1987 was applied. The model is suited to the contour extraction of deformable objects, For example, red blood cells.
