Accurate Eye center location

02 Sep 2010 (Updated 24 Apr 2011)

The following code can be used to accurately determine eye center of any image.

File Information
Description	The code has been tested successfully on a number of images. The algorithm is based on paper tiled "Accurate eye center location using isophote curature" presented by Roberto valenti and Theo Gevers at CVPR 2008 in ALASKA.
Required Products	Image Processing Toolbox
MATLAB release	MATLAB 7.9 (2009b)

02 Sep 2010	GAGAN	A simplistic approach to a complex problem.
07 May 2011	ru b	when I tried to run this code, it gave me the following error ??? Improper assignment with rectangular empty matrix. Error in ==> eyepoint at 219 [ro(gagan),c(gagan)]=find(X); Can somebody please help me with this
08 May 2011	GAGAN	It looks like you are using too high a value for parameters that's why it is giving a an empty array at line 219.
30 May 2011	dharshini	The code is working!! but the is not accurate..must i change the algorithm or sth.. pls help mi with that..thanks
30 May 2011	GAGAN	@dharshini What type of images r u working on. The value of parameters vary depending on image types. u can find the algorithm in the paper i have listed. Also if u r working with low resolution images u need a different way to calculate curvature. see the following link: http://staff.science.uva.nl/~mark/downloads.html
31 May 2011	dharshini	The image is when the webcam actually captures our face den its finds the center of the eye!!btw which paper??
31 May 2011	GAGAN	@dharshini this paper will help you: staff.science.uva.nl/~rvalenti/publications/CVPR08.pdf
23 Jun 2011	Matthew Sherwood	Does this code work for 16-bit thermal images (do I need to convert them to a jet or rgb?)?
23 Jun 2011	GAGAN	I think you need to convert your image to rgb.
