hi;

i want to do segmentation using FCM .For that, i tried the following coding for image segmentation. i am getting the error of " undefined function 'fcmthresh' for input arguments of type 'double' ".What should i do to rectify this error..please guide me..

%testfcmthresh.m
clear;clc;
im=imread('mliver3.jpg');
fim=mat2gray(im);
level=graythresh(fim);
bwfim=im2bw(fim,0.1);
[bwfim0,level0]=fcmthresh(fim,0);
[bwfim1,level1]=fcmthresh(fim,1);
subplot(2,2,1); imshow(fim);title('Original');
subplot(2,2,2); imshow(bwfim);title(sprintf('Otsu,level=%f',level));
subplot(2,2,3); imshow(bwfim0);title(sprintf('FCM0,level=%f',level0));
subplot(2,2,4); imshow(bwfim1);title(sprintf('FCM1,level=%f',level1)); % imwrite(bwfim1,'fliver6.jpg');
