Hi, from maybe a month I'm working on my bachelor thesis, that is based on OpenCV. But now I have one problem...

So here you can see that continuous function. From that 2d image I have to extract the amplitude of that function, but the problem is that there is some noise on the function it self ant in the area around it (lower part of the image).

So now the question is how to get the amplitude of that kind of signal ? I thought about median filtering or erosion/dilatation but I'm afraid, that with the erosion on some places I can destroy the function it self...
