This paper proposes a method of high-resolution remote sensing image of buildings on semi-automatic edge extraction. The first, pre-process remote sensing image and detecting all the edge; the second, tracking the edge and extracting linear feature, extracting the main direction line of the buildings; then using the model to judge the relations of line, segmentation and regional growth; lastly, merge regions and extract the building contour. The paper use this method to experiment on high-resolution Quick Bird satellite images, the result shows that this method has a higher recognition level, a better accuracy of a certain practical value. 1
