Since you are starting the unit on eye/vision, I have a great article from the Turkish Journal of Electrical Engineering & Computer Science.  The research article titled A video-based eye pupil detection system for diagnosing bipolar disorder, was published in 2013 by faculty members of Kirikkale University.

 

If you are interested in the article, please stop by my room.  When you are finished reading and annotating, return for 1-2 SAR questions.

 

Thanks and happy reading!
