• Abstract summary: We propose an end-to-end solution to jointly reconstruct room layout, object bounding boxes and meshes from a single image. Our method builds upon a holistic scene context and proposes a coarse-to-fine hierarchy with three components. Experiments on the SUN RGB-D and Pix3D datasets demonstrate that our method consistently outperforms existing methods.

• Abstract: Semantic reconstruction of indoor scenes refers to both scene understanding and object reconstruction. Existing works either address one part of this problem or focus on independent objects. In this paper, we bridge the gap between understanding and reconstruction, and propose an end-to-end solution to jointly reconstruct room layout, object bounding boxes and meshes from a single image. Instead of separately resolving scene understanding and object reconstruction, our method builds upon a holistic scene context and proposes a coarse-to-fine hierarchy with three components: 1. room layout with camera pose; 2. 3D object bounding boxes; 3. object meshes. We argue that understanding the context of each component can assist the task of parsing the others, which enables joint understanding and reconstruction. The experiments on the SUN RGB-D and Pix3D datasets demonstrate that our method consistently outperforms existing methods in indoor layout estimation, 3D object detection and mesh reconstruction.

• Disentangled 3D Scene Generation with Layout Learning [109.03233745767062]
  We introduce a method to generate 3D scenes that are disentangled into their component objects. Our key insight is that objects can be discovered by finding parts of a 3D scene that, when rearranged spatially, still produce valid configurations of the same scene. We show that despite its simplicity, our approach successfully generates 3D scenes into individual objects.

• Few-View Object Reconstruction with Unknown Categories and Camera Poses [80.0820650171476]
  This work explores reconstructing general real-world objects from a few images without known camera poses or object categories. The crux of our work is solving two fundamental 3D vision problems -- shape reconstruction and pose estimation. Our method FORGE predicts 3D features from each view and leverages them in conjunction with the input images to establish cross-view correspondence.

A novel structure is proposed, namely, textittrack-community, in which each community consists of a group of tracks and represents a local segment in the scene.

  We present a technique for a complete 3D reconstruction of small objects moving in front of a textured background. It is a particular variation of multibody structure from motion, which specializes to two objects only. In experiments with real artifacts, we show that our approach has practical advantages when reconstructing 3D objects from all sides.

  Estimating the 3D shape of an object from a single or multiple images has gained popularity thanks to the recent breakthroughs powered by deep learning. This paper proposes to rely on viewpoint variant reconstructions by merging the visible information from the given views. To validate the proposed method, we perform a comprehensive evaluation on the ShapeNet reference benchmark in terms of relative pose estimation and 3D shape reconstruction.

• CoReNet: Coherent 3D scene reconstruction from a single RGB image [43.74240268086773]
  We build on advances in deep learning to reconstruct the shape of a single object given only one RBG image as input. We propose three extensions: (1) ray-traced skip connections that propagate local 2D information to the output 3D volume in a physically correct manner; (2) a hybrid 3D volume representation that enables building translation equivariant models; and (3) a reconstruction loss tailored to capture overall object geometry. We reconstruct all objects jointly in one pass, producing a coherent reconstruction, where all objects live in a single consistent 3D coordinate frame relative to the camera and they do not intersect in 3D space.
