No compute method for cv::gpu::HOGDescriptor

edit

Hi,

I am trying to build a GPU accelerated SVM detector using HOG in OpenCV 2.4 (cannot upgrade to 3 right now unfortunately).

I have noticed that this function below does not exist in the cv::gpu implementation:

public void compute(Mat img,
       MatOfFloat descriptors,
       Size winStride,
       Size padding,
       MatOfPoint locations)

As I understand it, it is the method for computing the hog features for the image. I was wondering if it did exist in the gpu library under a different name?

I have looked through the source code here: https://github.com/Itseez/opencv/blob... but couldn't find something that looked like an equivalent, however I may have just missed it (I am quite new to HOG).

In short, does anyone know if this method exists in cv::gpu::HOGDescriptor under a different name?
