arithmetic_decoding.m

利用matlab开发平台针对算术编码原理实现了算术编码

% decoding
function [Mat]=arithmetic_decoding(m,n,color,allLow,allHigh,numberlow,numberhigh)
Mat = zeros(m,n);
for k = 1:m
   for kk = 1:n
       indx = numberlow<allLow;
       indx = [indx 1];
       ind = diff(indx);
       ind = logical(ind);
       Mat(k,kk) = color(ind);
       low = allLow(ind);
       high = allHigh(ind);
       range = high - low;
       numberlow = numberlow-low;
       numberlow = numberlow/range;
   end
end
