I am trying to use “findMinMaxLoc” function with streams (to speed up). I can retrive the minimum & maximum values successfully. But, I am unable to get the location points for the min and max. I will appreciate any help to retrieve the location points!

## Function I am using:

void cv::cuda::findMinMaxLoc   
(   
InputArray src,  
OutputArray minMaxVals,  
OutputArray loc,  
InputArray mask = noArray(),  
Stream & stream = Stream::Null()  
)
