Charts
In the following charts we compare time to unit variance (TTUV, render speed), the mean relative squared error (MRSE), and an estimate of the absolute bias. We compute the latter by subtracting a variance estimate of both images from the mean squared error (MSE) and then taking the square root.
TTUV (core hrs)
MRSE
Absolute bias
