Extract feature points from faces to track eye's movement

| Watch this File

File Information
Description

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.

I have downloaded your eye tracking matlab codes. I have added the folder to the matlab path. I'm using matlab2011, I have image acquisition toolbox, and I'm using windows 7, 32 bits. When I'm using "getFeatures" function, I receive the following error. Is it possible to help me to resolve it, please?

thanks Peter of this code, i just need to know how to run it?haw could i use this code to extract eyes from the face image

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.

thnks for !

01 Feb 2010 Peter Aldrian

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

01 Feb 2010 monia ben mlouka

Does it work under MAC OSx?

thnks for your help

Do you added the folder to your path?

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

05 Dec 2009 Peter Aldrian

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.

05 Dec 2009 naufal mansor

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
[T] = getPoints(snapshot);

Hi Bree,

you are using windows7? Just delete the CloseRequestFcn.

This should work.

26 Nov 2009 Bree

I tried to run these codes, but it failed with the error message below:
=========================================
??? Error using ==> close>request_close at 185
Undefined function or method 'my_closereq' for input arguments of type 'videoinput'.

Error in ==> close at 99

Error in ==> eyetracking at 17
close all;

Caused by:
Error while evaluating figure CloseRequestFcn
=============================================

Does somebody have solution for this error?

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.
