i know that opencv 2.4.x had explicit support for opencl. now in open cv 3.0 there isn't an explicit support, but i understood from documentation that there is implicit support behind the scenes.

my question is that: Is there is opencl implementation for ORB descriptor? if so how can i use it?

As you can see on this line of code there is a specific openCL implementation of the ORB feature calculation in 3.0. Basically this means that if you have built openCV with the parameter -D WITH_OPENCL=ON in CMAKE, then this function will be called.

If not the general C++ interface without OpenCL support will be used.
