ihuffman.m

EZW implementation which will use wavelet transforms and do the compression decompression using EZW

function decode_x=ihuffman(encode_x,h,sortindex)
len=length(encode_x);
decode_x=[];
for i=1:4:len,
  if encode_x(1,i:i+3)==h(find(sortindex==1),1:4);
     decode_x=[decode_x,'p'];
  end
  if encode_x(1,i:i+3)==h(find(sortindex==2),1:4);
     decode_x=[decode_x,'n'];
  end
  if encode_x(1,i:i+3)==h(find(sortindex==3),1:4);
     decode_x=[decode_x,'z'];
  end
  if encode_x(1,i:i+3)==h(find(sortindex==4),1:4);
     decode_x=[decode_x,'t'];
  end
end
