Edge Effects in Empirical Mode Decomposition
It has been a little over three years since I started working on a Python implementation of the Hilbert Huang Transform. When I first presented it at SciPy India 2011 (video) it was just a collection of small scripts, without packaging, testing or even docstrings. Over time PyHHT has garnered some interest, and I have, since the last few weeks, found the time to regularly work on it. I have been able to come up with a decent implementation of empirical mode decomposition, pretty much in line with everything described in the original paper by Huang et al. The other parts of HHT, like the Hilbert spectrum and its time frequency representations are right around the corner.
