CONTEXTUAL CLASSIFICATION OF POINT CLOUDS USING A TWO-STAGE CRF
In this investigation, we address the task of airborne LiDAR point cloud labelling for urban areas by presenting a contextual classification methodology based on a Conditional Random Field (CRF). A two-stage CRF is set up: in a first step, a point-based CRF is applied. The resulting labellings are t...
