Peak
Peak
Calculation of PRNU coefficients
to bring all pixels to the peak.
DFNC
Peak, Image Filtered
Peak, Image Filtered
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.
