I need to represent my signal as a set of transitions from one level to another, and I am interested in transitions that have relatively big amplitude 2000+.
I applied median filter to get rid of the high frequency part of the signal and result looks like this. Now I can take gradient and get set of transitions, and based on the magnitude of these transitions, keep only big one. So, I will get transition, corresponding to the left side of this peak, I will filter out transitions from the top. But I would like to have right side of this peak also to be represented as one nice 2000+ transition. But as you can see on the picture, there is small kink in the middle of the right side that will break my transition into 2 parts.
Is there some kind of a filter that will transform my signal and remove this kink?
