Oriented and Directional Chamfer Distance Losses for 3D Object Reconstruction From a Single Image

IEEE ACCESS, 10, 61631–61638.

By: J. Lu *, Z. Li*, J. Bai * & Q. Yu *

author keywords: Point cloud compression; Image reconstruction; Three-dimensional displays; Surface reconstruction; Costs; Shape; Feature extraction; Point cloud; single-view reconstruction; oriented chamfer distance; directional chamfer distance
TL;DR: Novel CD losses considering directions that can be used in a 3D reconstruction network are introduced, and have two specific variants, Oriented Chamfer distance (OCD) and Directional Chamfer Distance (DCD). (via Semantic Scholar)
