Motivation
| | Modern imaging methods like fluorescence x-ray imaging and multispectral imaging have been a great aid in this effort. The latter is a non-destructive technique that has been growing in the last years for painting investigation. Providing spectral and colorimetric characterization of the whole painted surface, it is suitable to document the conservation state of an artwork. Applying image mosaicing to multispectral imaging would produce very high resolution multispectral images of these artworks. Furthermore such a technique could facilitate higher image resolutions at the cost of an increased acquisition time. |
Goals
The students task is to prepare a documented software package that produces high resolution mosaic images of paintings (assuming these are flat) using a multispectral camera. The project will be split into following packages: acquisition, registration, stitching and post-processing and presentation. These work-packages will have some overlap as to offer the student time to asses the feasibility of each task, even before she/he focuses completely on it.Links

| Title: | Mosaicing Multi-spectral Images of Heritage Paintings |
| Abstract: | In this work we propose using multispectral imaging as an aid to the restoration process of heritage paintings and also to help peel back centuries of discoloration and layered impurities. To ensure that small enough details can be recovered, mosaicing will be employed to reconstruct a very high resolution image of the artworks in question. |
