Quick update. I have installed the unlicensed version on Server core 2019 (didn’t have the media for 2016) and it is all working great! It appears that core does support gui programs, it is just all the windows apps/desktop etc which is stripped out.
I have one issue though with blob detection. I get the error
“Error in Image Processing for Motion Detection
Exception Detail:The type initializer for ‘OpenCvSharp.CPlusPlus.NativeMethods’ threw an exception.”
which I assume some library is not installed. The issue seems to have been raised before at Error in image processing for Blob Detection
@Henrik did you manage to solve this?
