inherited

Calculates the image and overlap statistics, and then determines corrective factors if possible.

This method calculates image statistics on a band-by-band basis and calculates overlap statistics for the input images. Overlaps are considered valid if the number of valid pixels in the overlapping area is greater than or equal to the provided mincnt parameter. Corrective factors will only be determined if all of the input images have at least one valid overlap.

percent	Percentage of the lines to consider when gathering overall cube statistics and overlap statistics
mincnt	Minimum number of points in overlapping area required to be used in the solution
wtopt	Indicates whether overlaps should be weighted
methodType	An integer value corresponding to the enumerated value of the desired LeastSquares::SolveMethod to be used.

Exceptions

IException::Unknown	"Calculation for equalization statistics failed. Gain = 0."
IException::Unknown	"Unable to calculate the equalization statistics. You may " "want to try another LeastSquares::SolveMethod."
