摘要：
The object-oriented remote sensing change detection methods are increasingly used to extract Land-use change objects, and it's necessary to obtain vector borderline from the raster change objects for the purpose of spatial database updating process. A border vectorization method based on corner detection and curve fitting has been proposed in this paper. The method uses Curve Scale Space (CSS) algorithm with dynamic threshold of curvature to extract the corners in the edge images, and get the borderline of the image objects using B-spline curve fitting. The results show that the proposed method is practical and fast for accurate image objects boundary representation.
