... Since variance is the square of standard deviation, the obvious thing to to is to divide the input variance image by the square of the exposure map . Remember that, regardless of the value of readvarianceset , the task makes use of an internal variance image if either writevarianceset =`yes' or smoothstyle =`adaptive'.) ... However, recall that adaptive smoothing makes use of the input variance to calculate the signal-to-noise ratio (SNR) of the input image. ...
