Hi, I'm very new to matlab and now I need to implement skin detection using Baysian classification. I read a bit of tutorial for NaiveBayes and came out with the following:
P=imread('H:\skin.tif');
nbGau= NaiveBayes.fit(P(:,1:2), species);
nbGauClass= nbGau.predict(P(:,1:2));
is it the right way for training and sampling? if I'm still correct, how can I get "species" value?
Please inspire me of how to implement Bayesian classification in image processing... Thanks so much in advance!

What toolbox is all this stuff in? Can you add it to the Products below? It's not in the Image Processing Toolbox.

I think you are going through
1 load fisheriris
2 O1 = NaiveBayes.fit(meas,species);
3 C1 = O1.predict(meas);
4 cMat1 = confusionmat(species,C1)
The first line loads a double 2d matrix called as meas and also a cell of 150x1 displaying (See RHS workspace box) 'setosa' ... ... in your case i dont know what you want to classify but the steps you want to try must alter to the standard way. see
