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.

Target Calculation of PRNU coefficients to
bring all pixels to the target value.
