Computer Vision How are Computer Graphics and Computer Vision Related? Computer graphics in general Description of scene  Visual representation (Image) Computer Vision in general: Image(s)  Some description of the scene Example - Input: Image Output: Face locations Fujifilm camera demo

Computer Vision Many Subfields

Human-Computer Interaction We’re all used to mouse and keyboard… But you could use a camera to track motion… Camera Mouse http://www.cameramouse.org/ (Free Download) Articles and Videos: http://www.bu.edu/today/2009/the-seeing-eye-mouse/ http://www.bu.edu/today/2011/big-meaning-in-the-smallest-movements/ A user with severe paralysis using the Camera Mouse
