I work in computer vision and spoken language anlaysis. My advisor is Prof. Allan Jepson. My office is PT283E.

I like drama (principally the on-stage kind), playing guitar (complete lack of talent notwithstanding), watching TV, and wasting time on the internet.

I coördinate the weekly CSGSBS cookie breaks.

Object detection

I'm playing width object detection right now.

Background colour detection/rectangular object detection

For the background colour detection part, we describe a way to use the fact that the background colour appears in patches and the fact that we can predict the edge statistics of the background/non-background boundary.

We also describe a perceptual organization based rectangle detection algorithm, and use a large synthetically-generated set to tune the parameters.

The intended application is streamlining of the process of scanning in documents like photos and business cards using a flatbed scanner.

Photo orientation detection

We developed a system that determines the orientation of the input photo (from 0, 90, 180, and 270 degrees). You can try it if you have an Epson scanner.
