PLaMo 2.1-VL Technical Report

Tommi Kerola, Yuya Masuda, Takashi Masuko +5

We introduce PLaMo 2.1-VL, a lightweight Vision Language Model (VLM) for autonomous devices, available in 8B and 2B variants and designed for local and edge deployment with Japanes…

Warp-Refine Propagation: Semi-Supervised Auto-labeling via Cycle-consistency

Aditya Ganeshan, Alexis Vallet, Yasunori Kudo +5

Deep learning models for semantic segmentation rely on expensive, large-scale, manually annotated datasets. Labelling is a tedious process that can take hours per image. Automatica…

Hierarchical Lovász Embeddings for Proposal-free Panoptic Segmentation

Tommi Kerola, Jie Li, Atsushi Kanehira +3

Panoptic segmentation brings together two separate tasks: instance and semantic segmentation. Although they are related, unifying them faces an apparent paradox: how to learn simul…

Minimizing Supervision for Free-space Segmentation

Satoshi Tsutsui, Tommi Kerola, Shunta Saito +1

Identifying "free-space," or safely driveable regions in the scene ahead, is a fundamental task for autonomous navigation. While this task can be addressed using semantic segmentat…

Distantly Supervised Road Segmentation

Satoshi Tsutsui, Tommi Kerola, Shunta Saito

We present an approach for road segmentation that only requires image-level annotations at training time. We leverage distant supervision, which allows us to train our model using…

Pano2CAD: Room Layout From A Single Panorama Image

Jiu Xu, Bjorn Stenger, Tommi Kerola +1

This paper presents a method of estimating the geometry of a room and the 3D pose of objects from a single 360-degree panorama image. Assuming Manhattan World geometry, we formulat…
