Nice!
how exactly does one interpret the average probability ?
I mean if one frame is detecting a cat with 0.99 and one with 0.01
does that give a average of 0.5 ?
iam asking as that seems not the most usefull metric as two frames with
0.5 would be alot weaker indicator than one with 0.99 that there was at
least one cat (if these behave like standard probabilities)
thx
