VPI CUDA,OpenCV Interoperablity

[hhami.20401]

Hi guys,
I want use VPI library for Image processing.
“vpiImageSetWrappedOpenCVMat” function sets a OpenCV Mat to existing VPIImage without copy.
function “vpiImageCreateOpenCVMatWrapper” creats a VPIImage and copy content of existing OpenCV Mat to VPIImage with copy.
so my question is how to do it with OpenCV GPU Mat? I want a function like this to wrap OpenCV GPU Mat to VPI Image without copy (directly from GPU Mat to VPIImage).
Thanks so much.

Hi,

If you can get the CUDA buffer of gpuMat, please wrap it with the following API:

vpiImageCreateCUDAMemWrapper()

Thanks.
