multilevel thresholding by kapur method

whether the below code is correct for multilevel thresholding by kapur method close all clear all I =imread('C:\Users\swathi\Desktop\image1.gif'); level = 4; size(I,3) == 1 [n_countR, x_valueR] = imhist(I(:,:,1)); Nt = size(I,1) * size(I,2); Lmax = 256; for i = 1:Lmax size(I,3) == 1 PI(i) = n_countR(i) / Nt;

end N_PAR = level; dim = N_PAR; m = 256; n = dim; fitR = zeros(1,m); size(I,3) == 1 u = ones(1,dim) * Lmax; l = ones(1,dim); xR = zeros(m,n);

for j = 1: m PI0 = PI(1:xR(j,1)); ind = PI0 == 0; ind = ind .* eps; PI0 = PI0 + ind; clear ind w0 = sum(PI0); H0 = -sum((PI0/w0).*(log2(PI0/w0))); fitR(j) = fitR(j) + H0;

    for jl = 2: level
        PI0 = PI(xR(j,jl-1)+1:xR(j,jl)); 
        ind = PI0 == 0;
        ind = ind .* eps;
        PI0 = PI0 + ind;
        clear ind
        w0 =  sum(PI0); 
        H0 = -sum((PI0/w0).*(log2(PI0/w0)));
        fitR(j) = fitR(j) + H0;
    end  
end

Hii, Have you successfully done the multilevel kapur method? I need Multilevel Kapur code for comparative analysis of image with some other multilevel algorithm. Please help me by sending the Multilevel Kapur code.

I will be glad if you mail me the code : [e-mail]

Thank you.

I need Multilevel thresholding Kapur and Otsu code for my final year project.

I will be glad you mail me the the source code: [e-mail]

Thank You.
