IMG: Calibrating Diffusion Models via Implicit Multimodal Guidance

ICCV 2025poster

Ensuring precise multimodal alignment between diffusion-generated images and input prompts has been a long-standing challenge. Earlier works finetune diffusion weight using high-quality preference data, which tends to be limited and difficult to scale up. Recent editing-based methods further refine…

OpenBias: Open-set Bias Detection in Text-to-Image Generative Models

CVPR 2024highlight

Text-to-image generative models are becoming increasingly popular and accessible to the general public. As these models see large-scale deployments it is necessary to deeply investigate their safety and fairness to not disseminate and perpetuate any kind of biases. However existing works focus on de…

PAIR Diffusion: A Comprehensive Multimodal Object-Level Image Editor

CVPR 2024poster

Generative image editing has recently witnessed extremely fast-paced growth. Some works use high-level conditioning such as text while others use low-level conditioning. Nevertheless most of them lack fine-grained control over the properties of the different objects present in the image i.e. object-…

Prompt-Free Diffusion: Taking "Text" out of Text-to-Image Diffusion Models

CVPR 2024poster

Text-to-image (T2I) research has grown explosively in the past year owing to the large-scale pre-trained diffusion models and many emerging personalization and editing approaches. Yet one pain point persists: the text prompt engineering and searching high-quality text prompts for customized results…

Smooth Diffusion: Crafting Smooth Latent Spaces in Diffusion Models

CVPR 2024poster

Recently diffusion models have made remarkable progress in text-to-image (T2I) generation synthesizing images with high fidelity and diverse contents. Despite this advancement latent space smoothness within diffusion models remains largely unexplored. Smooth latent spaces ensure that a perturbation…

Zero-Shot Generative Model Adaptation via Image-Specific Prompt Learning

CVPR 2023poster

Recently, CLIP-guided image synthesis has shown appealing performance on adapting a pre-trained source-domain generator to an unseen target domain. It does not require any target-domain samples but only the textual domain labels. The training is highly efficient, e.g., a few minutes. However, existi…

VideoINR: Learning Video Implicit Neural Representation for Continuous Space-Time Super-Resolution

CVPR 2022poster

Videos typically record the streaming and continuous visual data as discrete consecutive frames. Since the storage cost is expensive for videos of high fidelity, most of them are stored in a relatively low resolution and frame rate. Recent works of Space-Time Video Super-Resolution (STVSR) are devel…

Rethinking Text Segmentation: A Novel Dataset and a Text-Specific Refinement Approach

CVPR 2021poster

Text segmentation is a prerequisite in many real-world text-related tasks, e.g., text style transfer, and scene text removal. However, facing the lack of high-quality datasets and dedicated investigations, this critical prerequisite has been left as an assumption in many works, and has been largely…
