In plain words: From one RGB-D view, the system fills in a full 3D map of what is solid and what each part is, using image edges and a distance-to-surface trick to place colour in 3D. It beat the best similar end-to-end system on real scans by 6.9%.

Abstract · EdgeNet: Semantic Scene Completion from a Single RGB-D Image

Semantic scene completion is the task of predicting a complete 3D representation of volumetric occupancy with corresponding semantic labels for a scene from a single point of view. Previous works on Semantic Scene Completion from RGB-D data used either only depth or depth with colour by projecting the 2D image into the 3D volume resulting in a sparse data representation. In this work, we present a new strategy to encode colour information in 3D space using edge detection and flipped truncated signed distance. We also present EdgeNet, a new end-to-end neural network architecture capable of handling features generated from the fusion of depth and edge information. Experimental results show improvement of 6.9% over the state-of-the-art result on real data, for end-to-end approaches.
