HISTENTROPY10 - Entropy feature derived from (co)occurrence matrices.

Contents

Description

Compute the entropy feature defined in [HSD73] from (co)occurrence matrices following the same formula as the function HISTENTROPY2, but using the the $\log$ in base 10 instead.

Syntax

   E = HISTENTROPY10(Pij);

References

Function implementation

function E = histentropy10(pIJ, varargin)
pIJ(pIJ==0) = 1;
E = - sum(log10(pIJ(:)) .* pIJ(:));
end % end of histentropy10
