I am taking this image as my input and applying thresholding, median Blur and Watershed algorithm to extract buildings.Source Image

After applying Median blur and thresholding I am getting this result Thresh

Median blur helps to remove the text but how to segment out the roads?

are you aware, that those maps are generated from vector data, and that it is likely possible to access that data ?
