Hi, my collegue have done some test which seems to confirm that optimization parameter in OpenCV algorithm is equivalent to grid search.
If it's confirma by anybody, it's a very good news for me because SVM is powefull but, in my point of view, svm is not so powerfull without grid search. Can anybody confirm this ?
