Language-Guided Instance-Aware Domain-Adaptive Panoptic Segmentation

no code implementations4 Apr 2024 Elham Amin Mansour, Ozan Unal, Suman Saha, Benjamin Bejar, Luc van Gool

A key challenge in panoptic UDA is reducing the domain gap between a labeled source and an unlabeled target domain while harmonizing the subtasks of semantic and instance segmentation to limit catastrophic interference.

2D Feature Distillation for Weakly- and Semi-Supervised 3D Semantic Segmentation

no code implementations27 Nov 2023 Ozan Unal, Dengxin Dai, Lukas Hoyer, Yigit Baran Can, Luc van Gool

As 3D perception problems grow in popularity and the need for large-scale labeled datasets for LiDAR semantic segmentation increase, new methods arise that aim to reduce the necessity for dense annotations by employing weakly-supervised training.

Three Ways to Improve Verbo-visual Fusion for Dense 3D Visual Grounding

no code implementations8 Sep 2023 Ozan Unal, Christos Sakaridis, Suman Saha, Fisher Yu, Luc van Gool

A common formulation to tackle 3D visual grounding is grounding-by-detection, where localization is done via bounding boxes.

LiDAR Meta Depth Completion

1 code implementation24 Jul 2023 Wolfgang Boettcher, Lukas Hoyer, Ozan Unal, Ke Li, Dengxin Dai

While using a single model, our method yields significantly better results than a non-adaptive baseline trained on different LiDAR patterns.

Understanding Bird's-Eye View of Road Semantics using an Onboard Camera

1 code implementation5 Dec 2020 Yigit Baran Can, Alexander Liniger, Ozan Unal, Danda Paudel, Luc van Gool

In this work, we study scene understanding in the form of online estimation of semantic BEV maps using the video input from a single onboard camera.

Improving Point Cloud Semantic Segmentation by Learning 3D Object Detection

no code implementations22 Sep 2020 Ozan Unal, Luc van Gool, Dengxin Dai

Point cloud semantic segmentation plays an essential role in autonomous driving, providing vital information about drivable surfaces and nearby objects that can aid higher level tasks such as path planning and collision avoidance.
