Hi Nick -
    Think of the positive and negative pixels at a location as the net input to
the next layer of cells in the nervous system or the next system or process in
a computational model.  So it's algebraic summation of all the input at a point.

pixels below the line from the positive pixels above the line that are in the
same column? Or just add them up below the line? For example, if in one column
of output there are three pixels above the line and two below in the same
column, should we subtract the two pixels below from the three on top,
resulting in just one positive pixel above the line? Or should we just leave
three on top and two below?
