Collaborative Semantic Occupancy Prediction with Hybrid Feature Fusion in Connected Automated Vehicles

no code implementations12 Feb 2024 Rui Song, Chenwei Liang, Hu Cao, Zhiran Yan, Walter Zimmer, Markus Gross, Andreas Festag, Alois Knoll

Additionally, due to the lack of a collaborative perception dataset designed for semantic occupancy prediction, we augment a current collaborative perception dataset to include 3D collaborative semantic occupancy labels for a more robust evaluation.

VLTSeg: Simple Transfer of CLIP-Based Vision-Language Representations for Domain Generalized Semantic Segmentation

no code implementations4 Dec 2023 Christoph Hümmer, Manuel Schwonberg, Liangwei Zhou, Hu Cao, Alois Knoll, Hanno Gottschalk

We thus propose a new vision-language approach for domain generalized segmentation, which improves the domain generalization SOTA by 7. 6% mIoU when training on the synthetic GTA5 dataset.

Spatio-temporal Tendency Reasoning for Human Body Pose and Shape Estimation from Videos

no code implementations7 Oct 2022 Boyang Zhang, Suping Wu, Hu Cao, Kehua Ma, Pan Li, Lei Lin

Different from them, our STR aims to learn accurate and natural motion sequences in an unconstrained environment through temporal and spatial tendency and to fully excavate the spatio-temporal features of existing video data.

Event-based Robotic Grasping Detection with Neuromorphic Vision Sensor and Event-Stream Dataset

1 code implementation28 Apr 2020 Bin Li, Hu Cao, Zhongnan Qu, Yingbai Hu, Zhenke Wang, Zichen Liang

Based on the Event-Stream dataset, we develop a deep neural network for grasping detection which consider the angle learning problem as classification instead of regression.
