evaluation of segmentation image

2 次查看(过去 30 天)
I have this program that the evaluation of image segmentation, but I just can not run this program.
function [val] = IntraInter_LN(Imseg,Imori)
% function [val] = IntraInter_LN(Imseg,Imori)
% Calcul du critère d'évaluation Intra-Inter de Lévine & Nazif
% Imseg : matrice correspondant à l'image segmentée avec des valeurs allant de 1 à n pour les n régions segmentées
% Imori : matrice correspondant à l'image originale

if (min(min(Imseg))==0)

What happens when you try to run it?
What data class should the input images be? Should they be grayscale (2 dimensional) or RGB (3 dimensional) ?
