An Improved Refined Composite Multivariate Multiscale Fuzzy Entropy Method for MI-EEG Feature Extraction

Algorithm 1

The procedure for calculating IRCmvMFE.

Input: Channels selected data
(1)	Coarse-graining of IRCmvMFE
	Step 1. Calculate the output of median filter on :
	Step 2. Calculate the output of mean filter on :
(2)	IRCmvMFE calculation
	Step 1. Set embedding dimension m and scale factor , calculate the multivariate reconstruction vectors:
	Step 2. For k = 1 to
	Calculate the distance and the similarity of and using equations (5) to (6)
	Calculate by equation (7)
	End
	Step 3. Repeat the above steps, extend the dimension from to , and calculate
	Step 4. Set and , and calculate IRCmvMFE
Output: IRCmvMFE at scale
