Actually I am using data taken using photographic plates. So there are
six step wedge, each step wedge transmits light in different way, say
for example the first step will be the darker than the second one and
so on as the last step is lightest one. So if I take a column cut
along the data, I can find six step like profile. Now I need to
separate each step automatically to proceed further. So I thought if I
can fit a step function with the data and can find the turn over point
of each step. Please give some suggestions.
thanking you
