Statement of purpose My primary research objective and interest is in the area of computer graphics. I am currently studying computer science at Princeton University, and I am actively involved in a research project that is developing an automated system to assist archaeologists in reconstructing excavated frescoes. My work focuses in particular on analyzing fracture patterns from images of frescoes and developing a model of brittle fracture. This project has opened my eyes to a broad range of research in computer graphics and motivated me to undertake further study through a Ph.D. program. I am especially interested in problems of visualization, computational photography, and simulation, but I am open to trying new ideas as well.
Under the supervision of Professor Thomas Funkhouser, I conducted research that analyzed fracture patterns observed in frescoes excavated from Akrotiri (modern Santorini, Greece), an ancient Bronze Age city destroyed by earthquakes around the 17th century B.C. I developed a two-stage processing pipeline for this purpose. In the first stage, I used an interactive program to trace detailed fragment boundaries in high-resolution images of manually reconstructed frescoes. The output was a polygonal mesh, with each polygon representing a fragment. Next, I implemented geometric analysis algorithms to study the shapes and contacts of the fragment boundaries. Specifically, I produced statistical distributions of the lengths of cracks, the angles at which cracks met, the fragment areas, and the adjacencies found in fragment arrangements. The main contribution of my study is a statistical model for crack patterns of fractured frescoes, which can guide scoring functions used in computer-assisted fragment reconstruction algorithms and also suggest a generative model about fracture processes.
