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.

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.

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.
