Is it possible to instantiate cascadeclassifier with two different xmls ?

I want to detect an object within another object. Its not make sense to do all the pre processing (integral image, feature extraction etc...) again if I know that the second object is within the first one. The trivial way to do it is to find the first object and then set ROI for the other classifier. But then, we doing some of the job we have already done. So I wander if there is a way to do
mJavaDetector = new CascadeClassifier(mCascadeFile.getAbsolutePath());

but with more that one XML.

Thanks!

no, you can't.

to detect 2 different objects, you need 2 seperate CascadeClassifier instances, and load a seperate xml each.

"But then, we doing some of the job we have already done."

imho, that's not an issue. calculating the integral img for lena takes 0.001343 seconds on my box

(and imho you won't be able to share the feature extraction for different objects)
