Hello,
I want to perform something similar to the WATERSHED function but on a
1d vector rather than an 2d array. Ultimately,
I want to separate overlapping cells in digital images of plankton. It
is possible to perform a watershed operation
on one of my 2d images... but I am hoping to kill a number of bird's
with one stone by performing a watershed on a horizontal
profile of an image.
In order to do this I need to mimic the LABEL_REGION function on a
vector. I can think of a number of
ways of doing this... but they seem computationally expensive (lots of
WHERE's and connectedness checking.)
Am I reinventing the wheel? If so, where should I look for existing
routines? (I have checked the usual caches of
routines available from David F's links page.)
Thanks,
Ben
