A Robust Gradient Based Method for Building Extraction from LiDAR and Photogrammetric Imagery
Existing automatic building extraction methods are not effective in extracting buildings which are small in size and have transparent roofs. The application of large area threshold prohibits detection of small buildings and the use of ground points in generating the building mask prevents detection...
