PRNU calibration process.

Peak
Peak Calculation of PRNU coefficients to bring
all pixels to the peak.
Peak, Image Filtered
PeakFilter A low pass filter is applied to the average
line values before calculating the
coefficients. Use this algorithm if the
calibration target is not uniformly white
or if it is not possible to defocus the
image. Because of the low pass filter, this
algorithm is not able to correct pixel-to-
pixel variations and so it is preferable to
use the “Peak” algorithm.
