Let It Flow: Simultaneous Optimization of 3D Flow and Object Clustering

no code implementations12 Apr 2024 Patrik Vacek, David Hurych, Tomáš Svoboda, Karel Zimmermann

We identified the structural constraints and the use of large and strict rigid clusters as the main pitfall of the current approaches and we propose a novel clustering approach that allows for combination of overlapping soft clusters as well as non-overlapping rigid clusters representation.

POP-3D: Open-Vocabulary 3D Occupancy Prediction from Images

no code implementations NeurIPS 2023 Antonin Vobecky, Oriane Siméoni, David Hurych, Spyros Gidaris, Andrei Bursuc, Patrick Pérez, Josef Sivic

We describe an approach to predict open-vocabulary 3D semantic voxel occupancy map from input 2D images with the objective of enabling 3D grounding, segmentation and retrieval of free-form language queries.

Regularizing Self-supervised 3D Scene Flows with Surface Awareness and Cyclic Consistency

1 code implementation12 Dec 2023 Patrik Vacek, David Hurych, Karel Zimmermann, Patrick Perez, Tomas Svoboda

Learning without supervision how to predict 3D scene flows from point clouds is essential to many perception systems.

T-UDA: Temporal Unsupervised Domain Adaptation in Sequential Point Clouds

1 code implementation15 Sep 2023 Awet Haileslassie Gebrehiwot, David Hurych, Karel Zimmermann, Patrick Pérez, Tomáš Svoboda

Deep perception models have to reliably cope with an open-world setting of domain shifts induced by different geographic regions, sensor properties, mounting positions, and several other reasons.

Teachers in concordance for pseudo-labeling of 3D sequential data

1 code implementation13 Jul 2022 Awet Haileslassie Gebrehiwot, Patrik Vacek, David Hurych, Karel Zimmermann, Patrick Perez, Tomáš Svoboda

We propose to leverage sequences of point clouds to boost the pseudolabeling technique in a teacher-student setup via training multiple teachers, each with access to different temporal information.

Drive&Segment: Unsupervised Semantic Segmentation of Urban Scenes via Cross-modal Distillation

1 code implementation21 Mar 2022 Antonin Vobecky, David Hurych, Oriane Siméoni, Spyros Gidaris, Andrei Bursuc, Patrick Pérez, Josef Sivic

This work investigates learning pixel-wise semantic image segmentation in urban scenes without any manual annotation, just from the raw non-curated data collected by cars which, equipped with cameras and LiDAR sensors, drive around a city.

Artificial Dummies for Urban Dataset Augmentation

1 code implementation15 Dec 2020 Antonín Vobecký, David Hurych, Michal Uřičář, Patrick Pérez, Josef Šivic

This is achieved with a data generator (called DummyNet) with disentangled control of the pose, the appearance, and the target background scene.

Challenges in Designing Datasets and Validation for Autonomous Driving

no code implementations26 Jan 2019 Michal Uricar, David Hurych, Pavel Krizek, Senthil Yogamani

There is a large gap between academic and industrial setting and a substantial way from a research prototype, built on public datasets, to a deployable solution which is a challenging task.
