DreamOmni2: Multimodal Instruction-based Generation and Editing

CVPR 2026

Recent advancements in instruction-based image editing and subject-driven generation have garnered significant attention, yet both tasks still face limitations in meeting practical user needs. Instruction-based editing relies solely on language instructions, which often fail to capture specific edit

Concerto: Joint 2D-3D Self-Supervised Learning Emerges Spatial Representations

NeurIPS 2025poster

Humans learn abstract concepts through multisensory synergy, and once formed, such representations can often be recalled from a single modality. Inspired by this principle, we introduce Concerto, a minimalist simulation of human concept learning for spatial cognition, combining 3D intra-modal self-d…

DreamOmni: Unified Image Generation and Editing

CVPR 2025poster

Currently, the success of large language models (LLMs) illustrates that a unified multitasking approach can significantly enhance model usability, streamline deployment, and foster synergistic benefits across different tasks. However, in computer vision, while text-to-image (T2I) models have signifi…

Lyra: An Efficient and Speech-Centric Framework for Omni-Cognition

ICCV 2025poster

As Multi-modal Large Language Models (MLLMs) evolve, expanding beyond single-domain capabilities is essential to meet the demands for more versatile and efficient AI. However, previous omni-models have insufficiently explored speech, neglecting its integration with multi-modality. We introduce Lyra,…

VisionZip: Longer is Better but Not Necessary in Vision Language Models

CVPR 2025poster

Recent advancements in vision-language models have enhanced performance by increasing the length of visual tokens, making them much longer than text tokens and significantly raising computational costs.However, we observe that the visual tokens generated by popular vision encoders, such as CLIP and…

GroupContrast: Semantic-aware Self-supervised Representation Learning for 3D Understanding

CVPR 2024poster

Self-supervised 3D representation learning aims to learn effective representations from large-scale unlabeled point clouds. Most existing approaches adopt point discrimination as the pretext task which assigns matched points in two distinct views as positive pairs and unmatched points as negative pa…

Hierarchical Dense Correlation Distillation for Few-Shot Segmentation

CVPR 2023highlight

Few-shot semantic segmentation (FSS) aims to form class-agnostic models segmenting unseen classes with only a handful of annotations. Previous methods limited to the semantic feature and prototype representation suffer from coarse segmentation granularity and train-set overfitting. In this work, we…
