Detailed Description

Calculates statistics in the area of overlap between two projected cubes.

This class finds the overlap between two cubes. It allows the user to check whether or not two cubes overlap, and also creates a MultivariateStatistics object containing the data from each cube in the overlapping area. The cubes entered into the constructor for this class must both be projections, and must have the same projection parameters.

If you would like to see OverlapStatistics being used in implementation, see equalizer.cpp

Constructor & Destructor Documentation

Isis::OverlapStatistics::OverlapStatistics ( Isis::Cube x,
Isis::Cube y,
QString  progressMsg = "Gathering Overlap Statistics",
double  sampPercent = 100.0 
)

Constructs an OverlapStatistics object.

Compares the two input cubes and finds where they overlap.

Parameters:
x The first input cube
y The second input cube
progressMsg (Default value of "Gathering Overlap Statistics") Text for indicating progress during statistic gathering
sampPercent (Default value of 100.0) Sampling percent, or the percentage of lines to consider during the statistic gathering procedure
Exceptions:
Isis::iException::User - All images must have the same number of bands
