Arbitrary-Shaped Image Generation via Spherical Neural Field Diffusion

Jiyuan Xia, Yuanshen Guan, Ruikang Xu, Zhiwei Xiong

ICLR 2026poster

Existing diffusion models excel at generating diverse content, but remain confined to fixed image shapes and lack the ability to flexibly control spatial attributes such as viewpoint, field-of-view (FOV), and resolution. To fill this gap, we propose Arbitrary-Shaped Image Generation (ASIG), the fir…

RawMetaDiff: Unlocking Extreme Darkness from Dual-Exposure RAW with Meta-Guided Diffusion

Panjun Liu, Jiyuan Xia, Yuanshen Guan, Yong Li, Zhiqiang Lang, Ruikang Xu +4

CVPR 2026

Extreme low-light Raw image restoration remains challenging due to overwhelming noise and severe detail loss.In this paper, we exploit the potential of the dual-exposure setting for this severely ill-posed problem.Existing methods suffer from unreliable cross-exposure alignment, resulting in degrade
