Unveiling Perceptual Artifacts: A Fine-Grained Benchmark for Interpretable AI-Generated Image Detection

ICLR 2026poster

Current AI-Generated Image (AIGI) detection approaches predominantly rely on binary classification to distinguish real from synthetic images, often lacking interpretable or convincing evidence to substantiate their decisions. This limitation stems from existing AIGI detection benchmarks, which, desp…

When Preference Labels Fall Short: Aligning Diffusion Models from Real Data

ICML 2026poster

Preference alignment aims to guide generative models by learning from comparisons between preferred and non-preferred samples. In practice, most existing approaches rely on preference pairs constructed from model-generated images. Such supervision is inherently relative and can be ambiguous when bot…

Are High-Quality AI-Generated Images More Difficult for Models to Detect?

ICML 2025poster

The remarkable evolution of generative models has enabled the generation of high-quality, visually attractive images, often perceptually indistinguishable from real photographs to human eyes. This has spurred significant attention on AI-generated image (AIGI) detection. Intuitively, higher image qua…

Can We Achieve Efficient Diffusion Without Self-Attention? Distilling Self-Attention into Convolutions

ICCV 2025poster

Contemporary diffusion models built upon U-Net or Diffusion Transformer (DiT) architectures have revolutionized image generation through transformer-based attention mechanisms. The prevailing paradigm has commonly employed self-attention with quadratic computational complexity to handle global spati…

Delving into Cascaded Instability: A Lipschitz Continuity View on Image Restoration and Object Detection Synergy

NeurIPS 2025poster

To improve detection robustness in adverse conditions (e.g., haze and low light), image restoration is commonly applied as a pre-processing step to enhance image quality for the detector. However, the functional mismatch between restoration and detection networks can introduce instability and hinder…

Towards Understanding the Robustness of Diffusion-Based Purification: A Stochastic Perspective

ICLR 2025poster

Diffusion-Based Purification (DBP) has emerged as an effective defense mechanism against adversarial attacks. The success of DBP is often attributed to the forward diffusion process, which reduces the distribution gap between clean and adversarial images by adding Gaussian noise. Although this expla…
