An undergraduate research project by two computer science students could help in the management of national monuments and cultural heritage sites by monitoring visual changes over time.<\/p>\n

Rohitashwa Bagaria \u201914 and Kim Merrill (Pomona) are studying cell phone camera photos taken by fellow students and others of a color tile kiosk outside the Olin Science Center at Harvey Mudd College.<\/p>\n

They plan to reverse engineer the image processing software on the different mobile devices to access the raw data captured by each phone\u2019s camera lens.<\/p>\n

HMC students use their phone cameras to help gather data<\/p><\/div>\n

\u201cWe have several color tiles whose raw color values we know. We compare the color values of the images received to those raw values,\u201d said Bagaria. \u201cThese real-color images are comparable for different cameras, since the raw colors captured by any camera lens is the same. We can use this data to compare changes in the images of monuments taken at different days. This information would be valuable to archaeologists trying to preserve a monument.\u201d<\/p>\n

The ultimate goal is to place at cultural heritage sites kiosks, which invite tourists to take photos of the monument and the kiosk tiles and then email the shots to a designated address for collection and study. The data will let conservators and site managers develop a long-term image dataset that provides quantitative measurements. They can measure rates of change and evaluate restorations and repairs in real-time. At the moment, there is very little data like this available.<\/p>\n

\u201cTo make the data useful, it needs to be calibrated, and this project is part of that process,\u201d said Gregory Bearman, the students\u2019 technical advisor. An expert in applying electronic and spectral imaging to archeology, Bearman is president of Snapshot Spectra and imaging lead for the Israel Antiquities Authority.<\/p>\n

\u201cThe students had to learn about color spaces and color theory, and they had to write Matlab code and do linear algebraic stuff they study in school in order to do this work. But the benefit for them is less what they do specifically and more about what they learn doing something that is open ended,\u201d said Bearman. \u201cThere\u2019s a big difference between doing coursework and having someone say, \u2018here\u2019s a real problem, now solve it.\u2019\u201d<\/p>\n

The project is being conducted as part of HMC\u2019s computer science course, Independent Study in Cultural Heritage Conservation Science.<\/p>\n","protected":false},"excerpt":{"rendered":"
