Description

Hello,

would it be possible to add parameter in predict method to get result probabilities?

something like this:

predict(const Mat& samples, Mat* results=0, Mat* probabilities=0 )

I've looked at code for CvNormalBayesClassifier and there is even comment suggesting that this value is already present in the code (/* probability = exp( -0.5 * cur ) */) so i guess that it would it be fairly simple to make this value accessible.

Thanks.

Thank you for proposal. We cannot just add additional parameter to method in branch 2.4 right now, because it breaks binary compatibility with previous release. But I think it is possible in master.
