img= imread('C:\Users\Islam\Desktop\ball2.jpg');
Image = rgb2gray(img);
Image = Image(:);
[N M] = size(Image)
Count = zeros(256,1)
for i = 1:N
for j = 1:M
Count(Image(i,j)+1)=Count(Image(i,j)+1)+1;
end
end
prob = Count/(M*N)
symbols = 0:255;
[dict,avglen] = huffmandict(symbols,prob);
comp = huffmanenco(Image,dict)
imshow(img);
