| Abstract: | The road automatic (semi-automatic) extraction is a focal studied point of the city remote sensing. Based on the current road automatic (semi-automatic) extraction technique and combining the distinct street trees in the high-resolution remotely sensed image, this paper utilizes some methods in geonomy to implement the road automatic (semi-automatic) extraction and the rapid, automatic algorithms of the road size based on the street trees, including NDVI, thresholding segmentation, the relevant operators of... |
