NeRF-Det: Learning Geometry-Aware Volumetric Representation for Multi-View 3D Object Detection

Chenfeng Xu, Bichen Wu, Ji Hou +8

We present NeRF-Det, a novel method for indoor 3D detection with posed RGB images as input. Unlike existing indoor 3D detection methods that struggle to model scene geometry, our m…

Mask3D: Pre-training 2D Vision Transformers by Learning Masked 3D Priors

Ji Hou, Xiaoliang Dai, Zijian He +2

Current popular backbones in computer vision, such as Vision Transformers (ViT) and ResNets are trained to perceive the world from 2D images. However, to more effectively understan…

PCR-CG: Point Cloud Registration via Deep Explicit Color and Geometry

Yu Zhang, Junle Yu, Xiaolin Huang +2

In this paper, we introduce PCR-CG: a novel 3D point cloud registration module explicitly embedding the color signals into the geometry representation. Different from previous meth…

Exploring Data-Efficient 3D Scene Understanding with Contrastive Scene Contexts

Ji Hou, Benjamin Graham, Matthias Nießner +1

The rapid progress in 3D scene understanding has come with growing demand for data; however, collecting and annotating 3D scenes (e.g. point clouds) are notoriously hard. For examp…

RfD-Net: Point Scene Understanding by Semantic Instance Reconstruction

Yinyu Nie, Ji Hou, Xiaoguang Han +1

Semantic scene understanding from point clouds is particularly challenging as the points reflect only a sparse set of the underlying 3D geometry. Previous works often convert point…

RevealNet: Seeing Behind Objects in RGB-D Scans

Ji Hou, Angela Dai, Matthias Nießner

During 3D reconstruction, it is often the case that people cannot scan each individual object from all views, resulting in missing geometry in the captured scan. This missing geome…

3D-SIS: 3D Semantic Instance Segmentation of RGB-D Scans

Ji Hou, Angela Dai, Matthias Nießner

We introduce 3D-SIS, a novel neural network architecture for 3D semantic instance segmentation in commodity RGB-D scans. The core idea of our method is to jointly learn from both g…
