Identification of Alcoholism Based on Wavelet Renyi Entropy and Three-Segment Encoded Jaya Algorithm

Pseudocode 1

Pseudocode of wavelet Renyi entropy.

Step  1 Input a given brain image .

Step  2 Perform a -level wavelet decomposition, and obtained () subbands.

Step  3 For :

     Get the 256-bin histogram of the th subband wavelet coefficients;

     Obtain Renyi entropy with order of over the histogram.

    End

Step  4 Output the catenation of all Renyi entropy values of all subbands.
