I have a question about the "Bluring measure" metric...
This metric allows you to compare power of bluring of two images. If value of the metric for first picture is greater, than for second it means that second picture is more blurred, than first.
So, as lower the result as more blurred the pic is, right? Well, in which relation stays the result to the original? Coz for a NOP vs NOP compare I get a result of 8.7789 with one source and a 9.1208 with the next one. Shouldn't a NOP vs NOP compare always give the same result (ie. a 10... assuming that this is the "best/max possibel" result) coz its not blurred at all? Another thing I find confusing is the metrics interpretation of blurriness... While a "dumb" Unfilter(-15,-15) gives a result of 7.4068, denoisers which produce much higher quality "blurring" (at same comp level as unfilter) get a much worse result (below 7.0) It looks like the metric is not able to differentiate between noise, texture and edge detail blurring, but I think this would be a MUST to get proper results at all!
