This is the code to find the thresold
clc; clear all; close all;
i= imread('cameraman.jpg'); [m,n]=size(i); figure, imshow(i);
[rows, columns, numberOfColorBands] = size(i)
if numberOfColorBands > 1 i = i(:, :, 2); % Take green channel. end
[y x]=imhist(i)
figure(2), imhist(i);
p=y/(m*n);
t=100;
while true
disp(t);
m1=(x>t);
u1= sum(x(m1).*p(m1))/sum(p(m1));
m2=(x<=t);
u2= sum(x(m2).*p(m2))/sum(p(m2));
tnew=(u1+u2)/2;
if t==tnew
break;
else
t=tnew;
end
end
After finding the threshold, how can i redraw the histogram and also the cameraman image by using the new threshold value.
can anyone help me in this.
Thank you
