Research Interests
I'm interested in computer vision and machine learning, though my background is in computer systems.. I am co-advised by Martial Hebert and Rahul Sukthankar.

Other Code
ImageSpline: Matlab implementation of Burt and Adelson's (1983) multiresolution spline technique for building image mosaics. I extend it to automatically calculate optimal seams in the image. This package assumes that homographies from each image to a global coordinate system (target mosaic image) have been calculated.Links
