"...each one is characterized by one peak followed by a minimum point."
That's not what your image is showing, though. The 2nd red line is not on a local minimum point. I see about 3 minimal points between the segmented peak and the next peak to the right of your segmentation (there may be smaller local minima as well). This will make implementation of your rule difficult.
Perhaps you want the minimum point between peak n and peak n+1 which would move the 2nd red line to the right by about 1 uinit.
Is there a peak marker under the 2nd red line? If so, is it your intension to end the segmentation at the next peak?
What defines the first red line?
