Title: Registration and Matching of Large Geometric Datasets for Cultural Heritage

Over the last decade, there has been growing interest in acquiring
high resolution digital representations of cultural heritage.  This
includes not only high resolution photographs, but also detailed 3-D
models of statues, buildings, paintings, archeological objects, etc.
These applications raise a number of challenges in data management,
and in designing affordable acquisition systems which are practical,
efficient, and usable.

This thesis looks at how to handle alignment applications in this
framework.  We show how to align range scans in the presence of
calibration error, as is the case in large, high-resolution models
such as the Digital Michelangelo models.  At the other extreme, we
show how to align small fresco pieces from the Thera project
completely automatically; in this case each individual model is small,
but because there are tens of thousands of fragments, efficiency and
automation are paramount.  We also show how registration techniques
extend to the problem of matching these fragments to each other.
Finally, we look at the problem of aligning high-quality 2-D images of
these fragments to the 3-D models.
