Enhancing Creative Generation on Stable Diffusion-based Models

CVPR 2025poster

Recent text-to-image generative models, particularly Stable Diffusion and its distilled variants, have achieved impressive fidelity and strong text-image alignment. However, their creative generation capacity remains limited, as simply adding the term "creative" to prompts often fails to yield genui…

StyleKeeper: Prevent Content Leakage using Negative Visual Query Guidance

ICCV 2025poster

In the domain of text-to-image generation, diffusion models have emerged as powerful tools. Recently, studies on visual prompting, where images are used as prompts, have enabled more precise control over style and content. However, existing methods often suffer from content leakage, where undesired…

Training-Free Safe Text Embedding Guidance for Text-to-Image Diffusion Models

NeurIPS 2025poster

Text-to-image models have recently made significant advances in generating realistic and semantically coherent images, driven by advanced diffusion models and large-scale web-crawled datasets. However, these datasets often contain inappropriate or biased content, raising concerns about the generatio…

A Simple Early Exiting Framework for Accelerated Sampling in Diffusion Models

ICML 2024poster

Diffusion models have shown remarkable performance in generation problems over various domains including images, videos, text, and audio. A practical bottleneck of diffusion models is their sampling speed, due to the repeated evaluation of score estimation networks during the inference. In this work…

Direct Unlearning Optimization for Robust and Safe Text-to-Image Models

NeurIPS 2024poster

Recent advancements in text-to-image (T2I) models have greatly benefited from large-scale datasets, but they also pose significant risks due to the potential generation of unsafe content. To mitigate this issue, researchers proposed unlearning techniques that attempt to induce the model to unlearn p…

Generator Knows What Discriminator Should Learn in Unconditional GANs

ECCV 2022poster

"Recent methods for conditional image generation benefit from dense supervision such as segmentation label maps to achieve high-fidelity. However, it is rarely explored to employ dense supervision for unconditional image generation. Here we explore the efficacy of dense supervision in unconditional…

Few-shot Compositional Font Generation with Dual Memory

ECCV 2020poster

Generating a new font library is a very labor-intensive and time-consuming job for glyph-rich scripts. Despite the remarkable success of existing font generation methods, they have significant drawbacks; they require a large number of reference images to generate a new font set, or they fail to capt…
