I’m preparing my first lecture of the semester (to a class of 70 ?!), and planning to make the claim that computer vision algorithms really touch our lives much more than in the past. So what are those algorithms?
- OCR/handwritten character recognition.
- Face detection in digital SLR cameras
- Face tracking in webcams
- smart phone apps like Google Goggles
- panoramic photo stitching
- iPhoto face annotation
What other recent algorithms are fully automatic and widely in use in consumer electronics?

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.
