A dual-cue network for multispectral photometric stereo

作者:

Highlights:

• A novel dual-cue fused network is proposed for surface normal recovering, which exploits specular highlights, shadows and interreflections appearing in local image patches, meanwhile maintaining high-frequency details.

• Compared to previous multispectral photometric stereo algorithms, the proposed method requires no extra information and breaks the limitation of Lambertian surfaces.

• The Dual-cue fused network outperforms existing approaches in robustness under complex illumination.
