A system for indexing, searching, and visualizing large unstructured multimedia collections. Our horizontally scalable approach determines absolute position, direction of capture, and time for each piece of media. This metadata will facilitate navigation through map-based interfaces that support intuitive queries depending on time and location.

Large media organizations are exposed to liability from accidental unauthorized use of photographs, or use of inauthentic digitally manipulated photographs. Some manipulation of photographs is required in practice such as converting RAW images to JPEG, or adjusting white balance, which makes establishing authenticity and verifying licensing difficult. Our system automatically verifies photograph licensing with an auditable chain of provenance based on user-defined "acceptable" digital modifications.

Created a method for automatically converting a digital 3D model into a multilayer model: a parallel stack of high-resolution 2D images embedded within a semi-transparent medium. Multilayer models can be produced quickly and cheaply and provide a strong sense of an object's 3D shape and texture over a wide range of viewing directions.

An extremely accurate system for measuring the shape and appearance of objects using computer controller cameras and lights. This allows recreating the appearance of that object under any lighting conditions and from any camera direction with photorealistic accuracy.
If you're interested in learning more about the technology, visit the project page, read the SIGGRAPH 2010 paper, or my dissertation.
Interactive 3D visualizations of pottery and sculpture from the Ancient Mediterranean, Asia, Africa, and Ancient Americas. Each object in this catalog can be rotated and enlarged using simple touch gestures. A detailed description written by UVaM curators accompanies each piece and chronicles its history and cultural context.
