Passive Vision.

Downtown St. Louis.

Welcome.  I plan to use this blog to ideas for both research and teaching.  At the moment, I’m looking forward to teaching Computer Vision to a class of 60 (!) in the Spring semester.  One of the techniques we will cover is PCA.  The above picture has two parts.  The left is one frame of a time-lapse from a camera set up in my lab.  The right image is a false color image, where the red, green, and blue channels are made from the first 3 principle components.

PCA has long been used for things such as face recognition, but also highlights structural components of a scene captured over time by a static camera.
