Learning Latent Proxies for Controllable Single-Image Relighting

CVPR 2026

Single-image relighting is highly under-constrained: small illumination changes can produce large, nonlinear variations in shading, shadows, and specularities, while geometry and materials remain unobserved. Existing diffusion-based approaches either rely on intrinsic- or G-buffer-based pipelines th

ScalingAR: Scaling Confidence for Autoregressive Image Generation

ICML 2026poster

Test-time strategies have shown remarkable success in improving large language models, but their application to next-token prediction (NTP) autoregressive (AR) image generation remains largely underexplored. Existing test-time scaling (TTS) methods for visual autoregressive models (VAR) rely on freq…

Model Reveals What to Cache: Profiling-Based Feature Reuse for Video Diffusion Models

ICCV 2025poster

Video generation using diffusion models has shown remarkable progress, yet it remains computationally expensive due to the repeated processing of redundant features across blocks and steps. To address this, we propose a novel adaptive feature reuse mechanism that dynamically identifies and caches th…

Unveiling the Ignorance of MLLMs: Seeing Clearly, Answering Incorrectly

CVPR 2025poster

**M**ultimodal **L**arge **L**anguage **M**odels (MLLMs) have displayed remarkable performance in multimodal tasks, particularly in visual comprehension. However, we reveal that MLLMs often generate incorrect answers even when they understand the visual content. To this end, we manually construct a…

FSC: Few-point Shape Completion

CVPR 2024poster

While previous studies have demonstrated successful 3D object shape completion with a sufficient number of points they often fail in scenarios when a few points e.g. tens of points are observed. Surprisingly via entropy analysis we find that even a few points e.g. 64 points could retain substantial…
