Applies four
convolution kernels in succession (equivalent to calculating the
curvature in the horizontal, vertical, and two diagonal directions) and
then adds the resulting images together. The curvature values are
truncated above zero to enhance regions with high negative curvature
(ie, it enhances 'mountains' and suppresses 'valleys'). This procedure
is used by the DNA
Strand Lengths analysis procedure.
