How many color classes do you have? Are you sure SVM is the best approach - why do you want to use it? I think it's mainly for two class situations but there is a multi-class extension to it.
I have some color segmentation demos in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

You can go to the website http://www.mathworks.com/help/stats/support-vector-machines.html for more information, or type 'demo toolbox statistics' in your matlab command window suppose you have a statistical toolbox installed.

hello sir,
thank u for ur reply ..!! I have statistic toolbox , N got the option feature selection there . but how to proceed for SVM after that? and I have only one image , so how to check its accuracy , whether the classification is accurate or not??
