UltraDiff: Transferring High-Fidelity Priors to Compressed Latent Spaces for High-Resolution Image Generation

Jingjing Ren, Haitian Zheng, Haoyu Chen +5

High-resolution synthesis with Latent Diffusion Models (LDMs) faces a fundamental trade-off between computational cost and generative fidelity. This trade off is largely governed b…

PixelControl: Fine-Grained Condition Fidelity in Text-to-Image Diffusion

Xin Lin, Haodong Li, Zhifei Zhang +5

Controllable text-to-image diffusion models can often follow the global layout of spatial conditions, yet still violate fine-grained structures such as object boundaries, thin cont…

Tri-Prompting: Video Diffusion with Unified Control over Scene, Subject, and Motion

Zhenghong Zhou, Xiaohang Zhan, Zhiqin Chen +8

Recent video diffusion models achieve strong visual quality and temporal coherence, but still lack coordinated control over scene layout, customized subject identity, and camera/su…

PixPerfect: Seamless Latent Diffusion Local Editing with Discriminative Pixel-Space Refinement

Haitian Zheng, Yuan Yao, Yongsheng Yu +3

Latent Diffusion Models (LDMs) have markedly advanced the quality of image inpainting and local editing. However, the inherent latent compression often introduces pixel-level incon…

HBridge: H-Shape Bridging of Heterogeneous Experts for Unified Multimodal Understanding and Generation

Xiang Wang, Zhifei Zhang, He Zhang +11

Recent unified models integrate understanding experts (e.g., LLMs) with generative experts (e.g., diffusion models), achieving strong multimodal performance. However, recent advanc…

MetaShadow: Object-Centered Shadow Detection, Removal, and Synthesis

Tianyu Wang, Jianming Zhang, Haitian Zheng +7

Shadows are often under-considered or even ignored in image editing applications, limiting the realism of the edited results. In this paper, we introduce MetaShadow, a three-in-one…

Object-level Scene Deocclusion

Zhengzhe Liu, Qing Liu, Chirui Chang +6

Deoccluding the hidden portions of objects in a scene is a formidable task, particularly when addressing real-world scenes. In this paper, we present a new self-supervised PArallel…
