Thesis
Here's a copy of
my thesis and the
refs.bib BibTeX file that used with it. It has a lot of papers that I've found interesting while doing research for my thesis.
My thesis was about Video Stabilization and Object Localization with video from Small UAVs. I did all of the work in the
MAGICC Lab. Some demo videos of the early stages of the video stabilization portion of my research can be seen on the
MAGICC Lab video page.
Raytracing
I wrote a Raytracer that ran up to 10 times faster than other students' Raytracers and the rendered images were selected as the top images from the class.
Here are the rendered images:
This image was rendered in about 15-20 minutes and most students' Raytracers took several hours to render an image with only one of the two objects.
This was just a "just for fun" rendering using a ball centered in a "room" that I texture mapped with pictures from my apartment. Upon close inspection you can notice that objects not attached to the wall (the chair and my wife) don't "look right" and actually show up twice in the rendering, but it's a fun little thing and pretty decent for what someone can do with a digital camera and a few spare minutes.
