Detailed Description
G-API backends available in this OpenCV version.
G-API backends play a corner stone role in G-API execution stack. Every backend is hardware-oriented and thus can run its kernels efficiently on the target platform.
Backends are usually "black boxes" for G-API users – on the API side, all backends are represented as different objects of the same class cv::gapi::GBackend. User can manipulate with backends by specifying which kernels to use.

Function Documentation
◆ backend() [1/3]
| cv::gapi::GBackend cv::gapi::cpu::backend | ( | ) |
#include <opencv2/gapi/cpu/gcpukernel.hpp>
Get a reference to CPU (OpenCV) backend.
This is the default backend in G-API at the moment, providing broader functional coverage but losing some graph model advantages. Provided mostly for reference and prototyping purposes.

◆ backend() [2/3]
| cv::gapi::GBackend cv::gapi::fluid::backend | ( | ) |
#include <opencv2/gapi/fluid/gfluidkernel.hpp>
Get a reference to Fluid backend.

◆ backend() [3/3]
| cv::gapi::GBackend cv::gapi::ocl::backend | ( | ) |
#include <opencv2/gapi/ocl/goclkernel.hpp>
Get a reference to OCL backend.
At the moment, the OCL backend is built atop of OpenCV "Transparent API" (T-API), see cv::UMat for details.
