   DEVIANT: Depth EquiVarIAnt NeTwork for Monocular 3D Object Detection

   Abhinav Kumar, Garrick Brazil, Enrique Corona, Armin Parchami, Xiaoming Liu

   Modern neural networks use building blocks such as convolutions that are equivariant to arbitrary 2D translations. However, these vanilla blocks are not equivariant to arbitrary 3D translations in the projective manifold. Even then, all monocular 3D detectors use vanilla blocks to obtain the 3D coordinates, a task for which the ...

   Voxel-based 3D Detection and Reconstruction of Multiple Objects from a Single Image

   Feng Liu, Xiaoming Liu

   Inferring 3D locations and shapes of multiple objects from a single 2D image is a long-standing objective of computer vision. Most of the existing works either predict one of these 3D properties or focus on solving both for a single object. One fundamental challenge lies in how to learn an ...

   GrooMeD-NMS: Grouped Mathematically Differentiable NMS for Monocular 3D Object Detection

   Abhinav Kumar, Garrick Brazil, Xiaoming Liu

   Modern 3D object detectors have immensely benefited from the end-to-end learning idea. However, most of them use a post-processing algorithm called Non-Maximal Suppression (NMS) only during inference. While there were attempts to include NMS in the training pipeline for tasks such as 2D object detection, they have been less widely ...

   Kinematic 3D Object Detection in Monocular Video

   Garrick Brazil, Gerard Pons-Moll, Xiaoming Liu, Bernt Schiele

   Perceiving the physical world in 3D is fundamental for selfdriving applications. Although temporal motion is an invaluable resource to human vision for detection, tracking, and depth perception, such features have not been thoroughly utilized in modern 3D object detectors. In this work, we propose a novel method for monocular video-based ...

   M3D-RPN: Monocular 3D Region Proposal Network for Object Detection

   Garrick Brazil, Xiaoming Liu

   Understanding the world in 3D is a critical component of urban autonomous driving. Generally, the combination of expensive LiDAR sensors and stereo RGB imaging has been paramount for successful 3D object detection algorithms, whereas monocular image-only methods experience drastically reduced performance. We propose to reduce the gap by reformulating the ...
