This project handles with the question how to extract fixed feature points from a given face in a real time environment. It is based on the idea, that a face is given by Viola Jones Algorithm for face detection and processed to track pupil movement in relation to the face without using infrared light.

@Yogesh Babu, could you teach me how you run the code? Which type of mex should i install to run it?

Jia Zhen

Hi, I have downloaded your eye tracking matlab codes. I have added the folder to the matlab path. But i cant seem to run the .m file as they said there are not enough input argument. What can i do to make it run?

Yogesh Babu

Hello,

Your code works fine !!!
but in order to find the eye poistion it takes more than 3 minutes....

Thank you for your code. The regions of Nose and lips are not correctly extracted.
Please, I want to ask you what is the reference which you used for determining the regions of eyes?

I have troubles to use the getFeatures function. I get the following error message although I added all subfolders to my path:
??? Invalid MEX-file '...\SCRIPTS\Fast Eyetracking\bin\FaceDetect.mexw32': The specified module could not
be found.
Is it because I did not download this toolbox:Image Acquisition Toolbox? But this toolbox is not for free right?
Thanks for your help.

cunming ?

thnks for !

As I know, the Image Acquisition Toolbox is just for Windows for now. So I'm sorry for all unix users

Does it work under MAC OSx?

thnks for your help

thanks a lot Peter,matlab7 not support clear vars..now I'm using matlabR2008b and its working just fine..i'm gong to do some modification and of course i'll keep your licence headers, and mention all of you in our acknowledgement sections in my thesis report..thanks a lot Peter.May god bless you

Peter Aldrian

Peter Aldrian (view profile)

I have no Idea what version of matlab you are using? clearvars is a matlab built in function... I hope the code will work without this line. So just delete the line.

I tried to run these codes, but it failed with the error message below:
=========================================
??? Undefined function or variable 'clearvars'.

Error in ==> getFeatures at 86
clearvars -except out

Does somebody have solution for this error?

Error in ==> getPoints at 39
out = getFeatures(snapshot0);

Error in ==> eyetracking at 48

Hi Bree,

you are using windows7? Just delete the CloseRequestFcn.

This should work.

We are working on a project called I-JAUS (please look for videos about it). We would like to add to our installation package your work, because it is perfect for showing how to control a robotic arm with the eyes.
Could you authorize us? Of course we'll keep your licence headers, and mention all of you in our acknowledgement sections (thesis report, and I-JAUS package).

It is important to add the bin-folder to the path. If somebody has problems, please write an email with your Exception.
