How does one use basic matrix operators with cv::UMat, similar to those available for cv::Mat. For example using ~ for bitwise_not, or comparing 2 matrices with >.
I'm aware of getMat, but I assume that using that function would remove the advantages of using UMat.
Also are there any efficiency differences between the 2 options below?
cv::UMat srcMat;
cv::Mat dstMat;
cv::cvtColor(srcMat, dstMat, CV_BGR2YUV);
uint8_t * data = dstMat.data;
or
cv::UMat srcMat, dstMat;
cv::cvtColor(srcMat, dstMat, CV_BGR2YUV);
uint8_t * data = dstMat.getMat(cv::ACCESS_READ).data;
