flat field algorithms.
Direct calculation of coefficients
based on average line values and
target. First each color is flat
field ed to its peak value and
then the color gains are used to
achieve the target.
A low p ass filter is first app lied
to the average line values before
calculating the coefficients. Use
this algorithm if the calibration
target is not uniformly w hite or
it is not possible to d efocus the
im age. Becau se of the low pass
filter this algorithm is not able to
correct pixel-to-pixel variations
and so it is preferable to u se the
―Basic‖ algorithm.
