generalized zero crossing #52

Hello, I would like to retrieve IMF frequencies. And I found this method generalized zero crossing(GZC) is used in some paper. Is it possible to implement this function in your library? :)

Hey,

Unfortunately, at the moment I'm rather busy with other projects and can't say when I'll be able to do something more on PyEMD. Not sure if I understand the motivation behind the GZC, seems like another "because it worked for us" algorithm, but I'm interested to see whether it'd be an interesting feature channel.

Will let you know next week (I'm on holidays now) whether I'll try to do this.

Nevertheless, thanks for the suggestion! It's always great to see what people are coming up with :-)

Hey, I decided not to implement this since the document you provided looks like a patent and I'm not sure what's the implication on the library. I don't want to change license of the PyEMD and definitely not force anyone to pay patent royalties. \
