This paper presents an automatic algorithm which reconstructs building models from airborne LiDAR (light detection and ranging) data of urban areas. While our algorithm inherits t...
The general approach for automatically driving data collection using information from previously acquired data is called active learning. Traditional active learning addresses the...
