Imagine processing, elimination of oscillations

Hi,

I need to follow only the max peacks of the figure shown. I want a figure without oscillations. How can I do?

What about the dip around 200? Do you want that to go straight across at 0.08, or still dip down?

You can use imdilate() which gives the max value inside a sliding window. Or just scan the data replacing with the max if it ever falls below the prior value.

out = inputSignal % Make copy.
for k = 2 : length(out)
  if out(k) < out(k-1)
    out(k) = out(k-1);
  end
end
