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.
