Study on Automated Labeling for Area Graphic Feature Based on Integral Image

In this paper,we propose an automated labeling algorithm for area graphic features based on integral image.The key of this algorithm is choosing two random endpoints as diagonal vertexs,because integral image can quickly identify it the rectangle locates inside the area feature.In this paper,we design and implement the automated labeling algorithm for area features based on integral image.The experimental results show that the algorithm can locate the unmarked annotation's position quickly and accurately.The algorithm has been applied to the real estate system in Shenzhen cadastral mapping unit.
