20 Jun 2007 (Updated 01 Jul 2009)

This function remove spike noise from data.

File Information
Description	This function remove spike noise from data. This function originally wrote for removing spike noise in time-series water velocity data but can be used for general purpose. The basic idea comes from Goring and Nikora (2002) which considers first and second derivatives of time series signal. See detail in the reference. Referece - Mori, N., T. Suzuki and S. Kakuno (2007) Noise of acoustic Doppler velocimeter data in bubbly flow, Journal of Engineering Mechanics, American Society of Civil Engineers, Volume 133, Issue 1, pp.122-125.

03 Jul 2007	D. Januar	Works realy fine with 3D face data, but some interpolation algorithm for filling the holes would be fine!
08 Aug 2007	landulfo Silveira	The algorithm leaves NAN symbols in the place of removed spikes. I coudn't use it.
03 Sep 2007	Evaggelos Karvounis	Dear Mr. Nobuhito, Could you please send me the paper again. There were errors when i was trying to open the pdf gile. Send it as a pdf and in a zip file if its possible. Thanks in advance... Evaggelos Karvounis, PhD
