Sim-to-Real Grasp Detection with Global-to-Local RGB-D Adaptation

no code implementations18 Mar 2024 Haoxiang Ma, Ran Qin, Modi shi, Boyang Gao, Di Huang

This paper focuses on the sim-to-real issue of RGB-D grasp detection and formulates it as a domain adaptation problem.

Covert Planning against Imperfect Observers

no code implementations25 Oct 2023 Haoxiang Ma, Chongyang Shi, Shuo Han, Michael R. Dorothy, Jie Fu

This paper studies how covert planning can leverage the coupling of stochastic dynamics and the observer's imperfect observation to achieve optimal task performance without being detected.

RGB-D Grasp Detection via Depth Guided Learning with Cross-modal Attention

no code implementations28 Feb 2023 Ran Qin, Haoxiang Ma, Boyang Gao, Di Huang

Planar grasp detection is one of the most fundamental tasks to robotic manipulation, and the recent progress of consumer-grade RGB-D sensors enables delivering more comprehensive features from both the texture and shape modalities.

Towards Scale Balanced 6-DoF Grasp Detection in Cluttered Scenes

1 code implementation10 Dec 2022 Haoxiang Ma, Di Huang

Moreover, a Scale Balanced Learning (SBL) loss and an Object Balanced Sampling (OBS) strategy are designed, where SBL enlarges the gradients of the samples whose scales are in low frequency by apriori weights while OBS captures more points on small-scale objects with the help of an auxiliary segmentation network.

Boundary Guided Context Aggregation for Semantic Segmentation

1 code implementation27 Oct 2021 Haoxiang Ma, Hongyu Yang, Di Huang

The recent studies on semantic segmentation are starting to notice the significance of the boundary information, where most approaches see boundaries as the supplement of semantic details.

Attention-Based Planning with Active Perception

no code implementations30 Nov 2020 Haoxiang Ma, Jie Fu

By switching between different attention modes, the robot actively perceives task-relevant information to reduce the cost of information acquisition and processing, while achieving near-optimal task performance.
