Description:
Optical techniques (2D and 3D) have found many applications in the field of Cultural Heritage. 3D imaging by structured light provides a 3D model of a object with high resolution, also in underwater environment. Underwater imaging is a difficult task due to the poor light conditions.
Multispectral imaging is an important method used in virtual restoration, to study ancient documents affect by degradations. Restoration involves different steps: image registration, image enhancement (statistical decorrelation) and image segmentation.
