The teaching methodology consists of a lecture of 2 hours per week and a laboratory class of 3 hours.
Lectures tackle the concepts listed in the syllabus. Whenever possible, problems will be solved as an example of theory taught during the class.
Laboratory classes include two projects.
The first project allows students to practice the concepts of digital image processing as a way to simulate the restoration of a damaged piece.
The topic of the second project is centered on using knowledge acquired during classes about 3D imaging.
- Two tests that deal with both theoretical and laboratory knowledge.
- A project of digital treatment as a way to simulate an original restoration.
- A project where students will develop simplified 3D annotated models of artistic installations.
