An Asymmetric Augmented Self-Supervised Learning Method for Unsupervised Fine-Grained Image Hashing

CVPR 2024poster

Unsupervised fine-grained image hashing aims to learn compact binary hash codes in unsupervised settings addressing challenges posed by large-scale datasets and dependence on supervision. In this paper we first identify a granularity gap between generic and fine-grained datasets for unsupervised has…

TM2B: Transformer-Based Motion-to-Box Network for 3D Single Object Tracking on Point Clouds

RA-L 2024

3D single object tracking plays a crucial role in numerous applications such as autonomous driving. Recent trackers based on motion-centric paradigm perform well as they exploit motion cues to infer target relative motion across successive frames, which effectively overcome significant appearance va

Hyperbolic Space with Hierarchical Margin Boosts Fine-Grained Learning from Coarse Labels

NeurIPS 2023poster

Learning fine-grained embeddings from coarse labels is a challenging task due to limited label granularity supervision, i.e., lacking the detailed distinctions required for fine-grained tasks. The task becomes even more demanding when attempting few-shot fine-grained recognition, which holds practic…

Underwater multi-robot convoying using visual tracking by detection

IROS 2017poster

We present a robust multi-robot convoying approach that relies on visual detection of the leading agent, thus enabling target following in unstructured 3-D environments. Our method is based on the idea of tracking-by-detection, which interleaves efficient model-based object detection with temporal f…

Learning legged swimming gaits from experience

ICRA 2015poster

We present an end-to-end framework for realizing fully automated gait learning for a complex underwater legged robot. Using this framework, we demonstrate that a hexapod flipper-propelled robot can learn task-specific control policies purely from experience data. Our method couples a state-of-the-ar…
