Please look at the first image (see links below). It is a GPR profile and using image processing techniques, I am trying to divide this image into 3 zones by labeling with colors the whole image on the top:

1) when parabolas in the image are very clear and distinct with high pixel values - green zone/ line at the top

2) when parabolas in the image are blurred but visible - yellow zone

3) when parabolas are distorted or when not parabolas are present - red zone

What techniques should I use? What's the best approach to solve it?

I have tried various techniques but not with success in every case, because, as you can in the second image (see link below) , sometimes the parabolas are too close to one another and identifying them is becoming an issue.

The third image (see link below) is a sample of how I wanted to do color coding:
