Connectionists: Fast code for multivariate empirical mode decomposition (MEMD)

[Danilo P. Mandic]

Dear All,

the following link may be of interest to the Connectionists community

http://www.commsp.ee.ic.ac.uk/~mandic/research/emd.htm

If you click on the 'Matlab' icon, you can download the Matlab code for 
multivariate EMD  (MEMD), which is now up to 10 times faster. There are 
also some supporting *.m and *.mat files.

MEMD extends the concept of single channel EMD, and allows you to 
simultaneously perform decomposition into oscillatory and AM/FM modes of 
any number of data channels - for instance you can use it to perform a 
simultaneous data-driven time-frequency analysis of a number of EEG 
channels.

The multivariate IMFs have common oscillatory modes across all the data 
channels, which facilitates both artifact removal and data/feature 
fusion across the data channels.

At the link above, there are articles using this method to analyse/fuse 
EEG, body motion from multiple 3D inertial bodysensors, and perform 
fusion of visual/thermal images and 'out of focus' image fusion.

Enjoy

Danilo
