Using a camera, how can I detect light intensity and use that as a marker. Can someone guide me to a thread that could help me develop a script for this.
Thank you

Use the Image Acquisition Toolbox and call getsnapshot(). Then get the intensity from whatever pixels you want in the image.

With Release R2014a you can now access the webcam without the Image Acquisition Toolbox. See http://www.mathworks.com/support/2014a/matlab/8.3/demos/webcam-support.html
