Extended Framework for Multispectral RTI

Reflectance transformation imaging (RTI) is a widespread technique for studying and documenting cultural heritage artifacts encompassing textural information. The principle capturing an object from static camera position by changing the direction of incident light in each image. coupling this approach with multispectral (Multispectral RTI) has shown promising results recent years. Considering approach, we propose expanded framework investigation documentation visual appearance surfaces, targeted to artifacts. In work, study integrated representation angular spectral components reflectance, as well contributions exploration independent wavelengths
