Common Inpainted Objects In-N-Out of Context

Tianze Yang, Tyson Jordan, Ruitong Sun, Ninghao Liu, Jin Sun

CVPR 2026

We present Common Inpainted Objects In-N-Out of Context (COinCO), a novel dataset addressing the scarcity of out-of-context examples in existing vision datasets. By systematically replacing objects in COCO images through diffusion-based inpainting, we create 97,722 unique images featuring both conte

RSTR: Reducing SpatioTemporal Redundancy in Diffusion Transformers

Ruitong Sun, Tianze Yang, Wei Niu, Jin Sun

ICML 2026poster

Diffusion Transformers (DiTs) have achieved remarkable success in image generation, yet their deployment is hindered by high computational costs. We identify two sources of redundancy. First, $\textbf{temporal redundancy}$: Classifier-Free Guidance (CFG) applies costly dual forward passes at every t…
