Hi everyone, this is my first time posting here.

I am trying to train my own SVM using features extracted using HoG. So far I can use the given pedestrian detector SVM for HoG to detect people. But I want to detect more poses, so I decided to train my own SVM using HoG.

My question is: Is there any OpenCV's API that allow me to extract HoG features and train a SVM later on ?

So far I couldn't find any answer, so I am trying to port HoG library from http://hogprocessing.altervista.org/ to C++, but I just realized that the developers use libsvm library, I am unsure whether I should also port that library.

Thank you very much !

Edit: I found libsvm library. But I am still wondering if there's any API directly from OpenCV that I can use, or any existing code regarding extracting HoG features within OpenCV's source code.

Thank you very much !
