The function performs non-max suppression if needed and returns the final amount of keypoints.
ocl::BRIEF_OCL
------------------
.. ocv:class:: ocl::BRIEF_OCL
Class for computing BRIEF descriptors described in a paper of Calonder M., Lepetit V.,
Strecha C., Fua P. *BRIEF: Binary Robust Independent Elementary Features* ,

ocl::BRIEF_OCL::BRIEF_OCL
--------------------------
Constructor.
.. ocv:function:: ocl::BRIEF_OCL::BRIEF_OCL(int bytes = 32)
:param bytes: The length of the descriptor in bytes. Supported values are 16, 32 or 64 bytes.
ocl::BRIEF_OCL::compute
------------------------
Computes BRIEF descriptors.
.. ocv:function:: void ocl::BRIEF_OCL::compute(const oclMat& image, const oclMat& keypoints, oclMat& mask, oclMat& descriptors) const
:param image: Image The input 8-bit grayscale image.
:param keypoints: The keypoints.
:param mask: In and output mask. If mask has same cols as keypoints, descriptors are computed for keypoints with non-zero mask element.
On return it indicates for what keypoints a descriptor was computed or not(if a keypoint is near the image border).
:param descriptors: The computed descriptors. It has size keypoints.cols x bytes.
ocl::BRIEF_OCL::getBorderSize
-----------------------------
Returns the size of the image border where descriptors cannot be computed
.. ocv:function:: static int ocl::BRIEF_OCL::getBorderSize() const
ocl::HOGDescriptor
----------------------
