AMD OpenCV Extension

The AMD OpenCV (vx_opencv) is an OpenVX module that implements a mechanism to access OpenCV functionality as OpenVX kernels. These kernels can be accessed from within OpenVX framework using OpenVX API call vxLoadKernels(context, "vx_opencv").

List of OpenCV-interop kernels

The following is a list of OpenCV functions that have been included in the vx_opencv module.
