- jononor 6y agoA measure that has consistently high agreement when evaluated by humans, repeatable across laboratories. Image quality tests can (and are) be conducted in a structured fashion.
- cycrutchfield 6y agoNo such measure exists, at least not one that can’t be gamed.
- jononor 6y agoNo if you allow / don't control for attempts to game it then no such metric can be made. One attempt to counter this is to use multiple independent labs.
