Thread Subject: face detection

guys i am doing a project about face gender classification, and one of the early steps in the project is face detection. I donot have that much knowledge about matlab but i want to start by face detection using hausdorff distance. Please can any body help how could start or how to start getting a binarized image using segmentation and localization or tell me where to search about this topic

Search on google:

hausdorff distance face detection

and

hausdorff distance face detection source matlab

And you'll find many links!

Hope this helps,

Michael


Best regards,

Omar I think haussdorf distance is the distance between two set of points for example between the 2 eyes of a person.

yes it determines both eyes and the distance between them and it is used for face detection.

I have a same assignement like you and I didn't know that this is haussdorf distance.

Hope my links helped you!

If you make this I need it too if you can help me I would be gratefull!

yeah would love to help u, but i really cannot even start making it on matlab i cant use it so im trying to learn it. secondly i want to finish my project in about a month which is a face gender classification program which I am lost in, i really dont know the procedures and my supervisor doesnt help that much.

It is also my case.

My e-mail address is mihaispr@yahoo.com.

Can you have a code for facial recognition using eigenfaces?

This part I have to finish.

Any ideas? Do you confront with this?

So I want that he compares me the photo loaded in axes to the bunch of photos from my directory and store in an edit a procent of recognition this part I want to make because I also don't have much time:(.

I wait your response!

At the risk of stating the obvious, have you looked here?

http://www.mathworks.com/matlabcentral/fileexchange/?term=Face+Recognition

There are quite a number of face recognition source code examples here including those based on the "Eigenface" methodology, several of which have 5 star ratings.

I haven't actually tried any of them, as I am no longer active in that field, but I would bet that its worth spending some time experimenting with them

So you say that you want to do face detection using Haussdorf distance.


For instance I'll make 2 steps:


1) Detecting the face

2) Marking on tooglebutton click the eyes of that person that you store in an axes component of a gui matlab

3) Detect the coordinates of the 2 points

4) Compute the distance Hausdorff which represents the distance between 2 points that is done by this mathematical formula:


Assuming your 2 points have A(x1,y1) and B(x2,y2) you compute the distance Hausdorff(between 2 points) as:

Formula for distance Hausdorff:

distance_Hausdorff=sqrt( (x1-x2)*(x1-x2) + (y1-y2)*(y1-y2) ) ; for instance is the generalisde Pytagora theorem in analytical geometry.

Here's a very good link for face detection:

i have code of your project i will send to u but i need face detection code if u send to me then i will send to u
