Null furrowed pixels
Description
This program works by finding the correlation between the columns
in an input image. With a Channel 0 image, the first five columns
are examined; in a Channel 1 image, the last five columns are
examined (Channel 2 images are not supported). If the statistical
results suggest a furrow is detected (i.e. the correlation between
two columns is below a certain threshold), then the affected column is
replaced with Null pixels.
If a an input image does not have a furrow, none of its pixels will be
altered. The label of all output files will include a new group called
"Correlations." This group lists the correlations between the relevant
columns. For example, "Column3to2 0.987..." means there is a strong
positive correlation between columns 2 and 3 (and very unlikely to have
a furrow in the area).

CORRELATION
Description
The maximum correlation from pixel to pixel. If the correlation
between two pixels suddenly drops below this value, then a furrow
has been detected.
