Our approach fuses gonioreflectometric measurements of small samples with few constraint images taken on a flatbed scanner under semi-controlled conditions. Underlying our method is a lightweight texture synthesis scheme using a local texture descriptor that combines shading and albedo across devices. Since it operates directly on SVD-compressed BTF data, our method is computationally efficient and can be implemented on a moderate memory footprint.I.3.3 [Computer Graphics]Picture/Image GenerationDigitizing and scanningI.3.7 [Computer Graphics]Three Dimensional Graphics and RealismColorshadingshadowingand texture10.2312/vmv.20151269143-150
