A	Feature extraction utilizing all 8 channels
1.	Find a ID set $X_1$ of Fx,   if   ${\sum }_{C1}^{C8}{P}_{Fx}>1$;
	Find a ID set Y of Fx,    if   ${\sum }_{C1}^{C8}{H}_{Fx}<6$;
	$Z_1=X\cup Y;$
	$>>$$Z_1$ = [2, 3, 4, 5, 6, 10, 18, 19, 29, 34, 37, 47, 56];
2.	Find $Z_2$ = [1, 8, 9, 14, 15, 17, 25, 31, 32, 35, 36, 40, 44, 45, 48, 49, 51, 60];
3.	Find a ID set $X_{0.5}$ of Fx,   if   ${\sum }_{C1}^{C8}{P}_{Fx}>0.5$;
	$Z_3=X_{0.5}\cap Z_2;>>$$Z_3$ = [9, 15, 31, 35, 45, 49];
