FlashNormal method uses flash/no-flash images for detailed surface normal estimation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed FlashNormal, a new diffusion-based method for estimating detailed surface normals using pairs of flash and no-flash images. This approach aims to improve upon single-image methods by leveraging the shading variations introduced by a flash, effectively reducing ambiguity between shape and reflectance. To support evaluation, a new dataset called EvalFlash has been created, featuring 20 objects with ground-truth surface normals for quantitative benchmarking. AI

IMPACT This method could improve 3D reconstruction and editing capabilities for applications using smartphone cameras.

    FlashNormal: Detailed Surface Normal Estimation from Flash and No-Flash Images

    arXiv:2608.25360v1 Announce Type: new Abstract: High-quality surface normal estimation is preferred for detailed surface shape recovery and image editing. Existing single image-based methods, though being a practical setup, often struggle to recover fine surface details and are s…
