• Abstract: We present a new pipeline for holistic 3D scene understanding from a single image, which could predict object shape, object pose, and scene layout. As it is a highly ill-posed problem, existing methods usually suffer from inaccurate estimation of both shapes and layout especially for the cluttered scene due to the heavy occlusion between objects. We propose to utilize the latest deep implicit representation to solve this challenge. We not only propose an image-based local structured implicit network to improve the object shape estimation, but also refine 3D object pose and scene layout via a novel implicit scene graph neural network that exploits the implicit local object features. A novel physical violation loss is also proposed to avoid incorrect context between objects. Extensive experiments demonstrate that our method outperforms the state-of-the-art methods in terms of object shape, scene layout estimation, and 3D object detection.

  Implicit neural fields have made remarkable progress in reconstructing 3D surfaces from multiple images. Previous work has attempted to tackle this problem by introducing a framework to train separate signed distance fields. We introduce our method, ObjectCarver, to tackle the problem of object separation from just click input in a single view.

  KYN is a novel method for single-view scene reconstruction that reasons about semantic and spatial context to predict each point's density. We show that KYN improves 3D shape recovery compared to predicting density for each 3D point in isolation. We achieve state-of-the-art results in scene and object reconstruction on KITTI-360, and show improved zero-shot generalization compared to prior work.

  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.
