Explicit3D: Graph network with spatial inference for single image 3D object detection

Yanjun Liu, Wenming Yang

Abstract: Highlights•We propose a sparse graph-based pipeline for single image 3D indoor scene detection.•A novel relatedness score guides dynamic pruning for sparse scene graph generation.•Homogeneous matrices are used to explicitly represent relative spatial relationships.•A novel relative loss boosts spatial offset prediction and overall object detection.
