Towards Learning to Complete Anything in Lidar

no code implementations16 Apr 2025 Ayca Takmaz, Cristiano Saltori, Neehar Peri, Tim Meinhardt, Riccardo de Lutio, Laura Leal-Taixé, Aljoša Ošep

However, contemporary methods can only complete and recognize objects from a closed vocabulary labeled in existing Lidar datasets.

Zero-Shot 4D Lidar Panoptic Segmentation

no code implementations CVPR 2025 Yushan Zhang, Aljoša Ošep, Laura Leal-Taixé, Tim Meinhardt

Zero-shot 4D segmentation and recognition of arbitrary objects in Lidar is crucial for embodied navigation, with applications ranging from streaming perception to semantic mapping and localization.

SPAMming Labels: Efficient Annotations for the Trackers of Tomorrow

no code implementations17 Apr 2024 Orcun Cetintas, Tim Meinhardt, Guillem Brasó, Laura Leal-Taixé

Increasing the annotation efficiency of trajectory annotations from videos has the potential to enable the next generation of data-hungry tracking algorithms to thrive on large-scale datasets.

Better Call SAL: Towards Learning to Segment Anything in Lidar

1 code implementation19 Mar 2024 Aljoša Ošep, Tim Meinhardt, Francesco Ferroni, Neehar Peri, Deva Ramanan, Laura Leal-Taixé

We propose the SAL (Segment Anything in Lidar) method consisting of a text-promptable zero-shot model for segmenting and classifying any object in Lidar, and a pseudo-labeling engine that facilitates model training without manual supervision.

NOVIS: A Case for End-to-End Near-Online Video Instance Segmentation

no code implementations29 Aug 2023 Tim Meinhardt, Matt Feiszli, Yuchen Fan, Laura Leal-Taixe, Rakesh Ranjan

Until recently, the Video Instance Segmentation (VIS) community operated under the common belief that offline methods are generally superior to a frame by frame online processing.

DeVIS: Making Deformable Transformers Work for Video Instance Segmentation

1 code implementation22 Jul 2022 Adrià Caelles, Tim Meinhardt, Guillem Brasó, Laura Leal-Taixé

To reason about all VIS subtasks jointly over multiple frames, we present temporal multi-scale deformable attention with instance-aware object queries.

TrackFormer: Multi-Object Tracking with Transformers

2 code implementations CVPR 2022 Tim Meinhardt, Alexander Kirillov, Laura Leal-Taixe, Christoph Feichtenhofer

The challenging task of multi-object tracking (MOT) requires simultaneous reasoning about track initialization, identity, and spatio-temporal trajectories.

Lifting Layers: Analysis and Applications

1 code implementation ECCV 2018 Peter Ochs, Tim Meinhardt, Laura Leal-Taixe, Michael Moeller

A lifting layer increases the dimensionality of the input, naturally yields a linear spline when combined with a fully connected layer, and therefore closes the gap between low and high dimensional approximation problems.

Learning Proximal Operators: Using Denoising Networks for Regularizing Inverse Imaging Problems

1 code implementation ICCV 2017 Tim Meinhardt, Michael Moeller, Caner Hazirbas, Daniel Cremers

While variational methods have been among the most powerful tools for solving linear inverse problems in imaging, deep (convolutional) neural networks have recently taken the lead in many challenging benchmarks.
