  abstract = {In this paper, we focus on semantic point cloud classification taking into account standard failure
              cases reported in a variety of investigations. We present a hybrid two-step framework integrating
              classification, segmentation and semantic rules in a common end-to-end processing pipeline from
              irregularly distributed points to semantically labelled point clouds. The first step of our
              framework consists of a point-wise semantic point cloud classification based on rather intuitive,
              handcrafted, low-level geometric features extracted from local neighbourhoods of locally adaptive
              size. The second step of our framework consists of refining the point-wise classification results by
              considering semantic rules applied to geometric features extracted on the basis of an
              over-segmentation of the derived class-wise point clouds. We demonstrate the performance of our
              framework on a standard benchmark dataset for which we obtain a semantic labelling of high accuracy
              and high plausibility.},
