Very High-Resolution Image-Based Rendering with Motion Extraction

GOAL

Michael Naimark, who has recently visited UNC, has taken very high-resolution (35mm ASA 50 film), very well-registered stereoscopic, panoramic footage of historical locations around the world. I would like to apply image-based rendering techniques to this data (soon to be ours in the original film form, from which we can obtain digital copies), to result in a three-dimensional environment.

What I hope to contribute on top of existing techniques is:

MOTIVATION

This is one of the best-registered and highest-resolution stereoscopic data sets extant, and since UNC has in evans one of the biggest number crunchers being applied in research, an environment of unmatched realism could ideally result. Furthermore, these are no "example" locations such as someone's graphics lab; these are UNESCO-designated "in danger" World Heritage Sites, such as Jerusalem, Dubrovnik (Croatia), Timbuktu (Mali), and Angkor (Cambodia).

PERSONAL INTEREST

Working for Dr. Henry Fuchs, I am involved with applications that use image-based rendering, but I am not myself that conversant with the techniques. I'd like to get experience using them, and possibly extending them. Also in that project, I have tried with limited success to understand and modify our existing display code. Hopefully, I can start from first principles to create code that makes more sense (to myself, anyway).

DEMONSTRATION

The demonstration will be a run of the application that displays the resulting 3-D environment, possibly on the head-mounted display, but more likely just with mouse interaction.
