Basic
Basic
Direct calculation of coefficients
based on average line values and
target. First each color is flat
fielded to its peak value and
then the color gains are used to
achieve the target.
LowPass
LowPass
A low pass filter is first applied
to the average line values before
calculating the coefficients. Use
this algorithm if the calibration
target is not uniformly white or
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
―Basic‖ algorithm.
Calibration Target
flatfieldCalibrationTarget
Set a value between 0 and 255 to
which the flat field algorithm
will taget the image to.
