My current research interests are cryptographic security and image-based methods for creating virtual content.
The images-based modeling work is part of a broader mixed reality project. My colleagues and I devised a novel approach that enables users to create models by marking up the real world with pre-printed markers with predefined meanings that guide the system in creating models. The system creates models from user-captured images or video of the marked-up space. Our marker-based approach creates not only static models, but also models with interactive components. The marker-based approach simplifies the hard problem of reconstructing a model from images because the markers are easily detectable and their associated meanings simplify the geometric deduction. It also enables users to specify which parts of a scene should be included and handles certain clutter removal and occlusion issues because it renders what the markers indicate rather than what is seen. With markers, users can specify deviations from the physical scene. We are currently working on advancing various aspects of this approach, including the markup language, the markup strategies, and the geometric deduction. In addition to marker-based approaches, we have begun to pursue pure non-marker-based approaches, and hybrid approaches. We are also exploring 3D viewers that spatially integrate images with a model. Our video provides an overview of our approach and demonstrates an earlier version of our system. More details of our work can be found in our publications.
Starting in October 2009, colleagues and I began an exploratory project to understand and apply recent developments in methods for computing on and searching encrypted data.
I also continue to follow developments in quantum computing. Together with Wolfgang Polak, I wrote one of the first technical tutorials for non-physicists. We are currently in the final stages of a book solicited by MIT press. I continue to write technical expository articles in this field, and also have a few research papers in this area.
I am incredibly fortunate to have had the opportunity to work in many diverse areas, including multimedia, bioinformatics, modular robotics, genetic programming, hypertext, and geometric group theory, as well as cryptography, mixed reality, and quantum computing,
Some of my work and interests are reflected in my posts to FXPAL's blog.
