Mix3D: Out-of-Context Data Augmentation for 3D Scenes

1 code implementation5 Oct 2021 Alexey Nekrasov, Jonas Schult, Or Litany, Bastian Leibe, Francis Engelmann

Since scene context helps reasoning about object semantics, current works focus on models with large capacity and receptive fields that can fully capture the global context of an input 3D scene.

3D-MPA: Multi-Proposal Aggregation for 3D Semantic Instance Segmentation

1 code implementation CVPR 2020 Francis Engelmann, Martin Bokeloh, Alireza Fathi, Bastian Leibe, Matthias Niessner

We show that grouping proposals improves over NMS and outperforms previous state-of-the-art methods on the tasks of 3D object detection and semantic instance segmentation on the ScanNetV2 benchmark and the S3DIS dataset.

SAMP: Shape and Motion Priors for 4D Vehicle Reconstruction

1 code implementation2 May 2020 Francis Engelmann, Jörg Stückler, Bastian Leibe

In this paper, we propose to use 3D shape and motion priors to regularize the estimation of the trajectory and the shape of vehicles in sequences of stereo images.

Dilated Point Convolutions: On the Receptive Field Size of Point Convolutions on 3D Point Clouds

1 code implementation28 Jul 2019 Francis Engelmann, Theodora Kontogianni, Bastian Leibe

In a thorough ablation study, we show that the receptive field size is directly related to the performance of 3D point cloud processing tasks, including semantic segmentation and object classification.

Exploring Spatial Context for 3D Semantic Segmentation of Point Clouds

1 code implementation5 Feb 2018 Francis Engelmann, Theodora Kontogianni, Alexander Hermans, Bastian Leibe

The recently proposed PointNet architecture presents an interesting step ahead in that it can operate on unstructured point clouds, achieving encouraging segmentation results.

Keyframe-Based Visual-Inertial Online SLAM with Relocalization

no code implementations7 Feb 2017 Anton Kasyanov, Francis Engelmann, Jörg Stückler, Bastian Leibe

Our visual-inertial SLAM system is based on a real-time capable visual-inertial odometry method that provides locally consistent trajectory and map estimates.
