DreamCS: Geometry-Aware Text-to-3D Generation with Unpaired 3D Reward Supervision

ICLR 2026poster

While text-to-3D generation has attracted growing interest, existing methods often struggle to produce 3D assets that align well with human preferences. Current preference alignment techniques for 3D content typically rely on hardly-collected preference-paired multi-view 2D images to train 2D reward…

Unsupervised Modality Adaptation with Text-to-Image Diffusion Models for Semantic Segmentation

NeurIPS 2024poster

Despite their success, unsupervised domain adaptation methods for semantic segmentation primarily focus on adaptation between image domains and do not utilize other abundant visual modalities like depth, infrared and event. This limitation hinders their performance and restricts their application in…

CMDA: Cross-Modality Domain Adaptation for Nighttime Semantic Segmentation

ICCV 2023poster

Most nighttime semantic segmentation studies are based on domain adaptation approaches and image input. However, limited by the low dynamic range of conventional cameras, images fail to capture structural details and boundary information in low-light conditions. Event cameras, as a new form of visio…
