Towards accurate instance segmentation in large-scale LiDAR point clouds

1 code implementation6 Jul 2023 Binbin Xiang, Torben Peters, Theodora Kontogianni, Frawa Vetterli, Stefano Puliti, Rasmus Astrup, Konrad Schindler

Panoptic segmentation is the combination of semantic and instance segmentation: assign the points in a 3D point cloud to semantic categories and partition them into distinct object instances.

AGILE3D: Attention Guided Interactive Multi-object 3D Segmentation

no code implementations1 Jun 2023 Yuanwen Yue, Sabarinath Mahadevan, Jonas Schult, Francis Engelmann, Bastian Leibe, Konrad Schindler, Theodora Kontogianni

In an iterative process, the model assigns each data point to an object (or the background), while the user corrects errors in the resulting segmentation and feeds them back into the model.

Connecting the Dots: Floorplan Reconstruction Using Two-Level Queries

1 code implementation CVPR 2023 Yuanwen Yue, Theodora Kontogianni, Konrad Schindler, Francis Engelmann

Instead, we formulate floorplan reconstruction as a single-stage structured prediction task: find a variable-size set of polygons, which in turn are variable-length sequences of ordered vertices.

Interactive Object Segmentation in 3D Point Clouds

1 code implementation14 Apr 2022 Theodora Kontogianni, Ekin Celikkan, Siyu Tang, Konrad Schindler

We propose an interactive approach for 3D instance segmentation, where users can iteratively collaborate with a deep learning model to segment objects in a 3D point cloud directly.

Continuous Adaptation for Interactive Object Segmentation by Learning from Corrections

no code implementations ECCV 2020 Theodora Kontogianni, Michael Gygli, Jasper Uijlings, Vittorio Ferrari

Our approach enables the adaptation to a particular object and its background, to distributions shifts in a test set, to specific object classes, and even to large domain changes, where the imaging modality changes between training and testing.

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.

Know What Your Neighbors Do: 3D Semantic Segmentation of Point Clouds

no code implementations2 Oct 2018 Francis Engelmann, Theodora Kontogianni, Jonas Schult, Bastian Leibe

In this paper, we present a deep learning architecture which addresses the problem of 3D semantic segmentation of unstructured point clouds.
