Using manually input seed points combined with edge detection algorithms to identify endpoints in road extraction
Detailed Documentation
In practical applications, we can locate road endpoints for road extraction by combining manually input seed points with edge detection results. This approach enables more accurate determination of road start and end points, thereby improving the effectiveness and precision of road extraction. The implementation typically involves using edge detection operators like Canny or Sobel to generate edge maps, then applying connectivity analysis from seed points to trace road boundaries and identify terminal nodes through endpoint detection algorithms.
