Need Matlab code for Attribute classifier and Smile Classifier

[Yasminaaa]

Hello all :
as the Title said ,,, i'm warking in face recognition field,i will make recognition for faces ussing a new method known as ( Attribute and smile classifiers) i need a matlab code for this or for a part of this method
my steps is to
1- Extract features from a database of faces images
2-then input them into SVM ( support vector machine) for training and testing
Plz i need help , at least for the 1st step ( feature extraction) , the way they extract features in the paper i'm working with is as the following:
1st : i need to choose a pixel value type* RGB , HSV , Edge magnitude , or Edge Orrientation
2nd Normalization ( mean normalization & energy normalization ) will be done
3rd Aggregation ( using histogram or mean/variance)
Plz Help
best regards and Thanks in advance

hello yasminaa,
i am also using working on same project. i want to ask u that, fr clasifier, what method will u use? plz tell me........

I would suggest that you implement PHOG and classify it using SVM or other classifiers. Principle Component Analysis can give you a little less efficiency.

Yasmina, for face recognition you can simply use PCA algorithm. Anyway, if you are keen on doing the other way round, you should try implementing PHOG.
One advice: Working on RGB plane wouldn't give you suitable results. Try working on YCbCr model. It leads to better extraction.
