close all; clear all; clc; data=imread('cameraman.tif'); figure(1),imshow(data);

 h=imhist(data);
 h1=h(1:10:256);
 horz=1:10:256;
figure(2), stem(horz,h1,'fill')
 axis([0 255 0 15000])
 set(gca,'xtick',[0:50:255])
  set(gca,'ytick',[0:2000:15000])
 s=size(data)
   count =0;
 for x=1:256
     for y=1:256
         if data(x,y)==248
             count=count+1;
         end;
     end;
 end;
for x=1:256
     for y=1:256
     f=(1/2)*((sum((max(data)-data(x,y)).^4))*(count/65536))/(sum((max(data)-data(x,y)).^2))
         mf(x,y)=exp(-(max(data)-data(x,y)).^2/2*f);
         %fuzzification
         I=(mf(x,y)./data(x,y));
         end;
     end;

error is ??? Undefined function or method 'exp' for input arguments of type 'uint8'. Error in ==> ann at 26 mf(x,y)=exp(-(max(data)-data(x,y)).^2/2*f);
