I am currently doing the image compression by using run length method. So far I had done the part of encoding. However, I am now facing the problem of doing the part of decoding. Is there any way that can be done to do for decoding the compressed image? Below is my encoding coding for run length compression.
function Output=rle2(y)
x=imread('nc_linggi.tif');
y=x(:,:,2);
L=length(y);
j=1;
k=1;
i=1;
while i<2*L
comp=1;
for j=j:L
if j==L
break
end;
if y(j)==y(j+1)
comp=comp+1;
else
break
end;
end;
Output(k+1)=comp;
Output(k)=y(j);
if j==L && y(j-1)==y(j)
break
end;
i=i+1;
k=k+2;
j=j+1;
if j==L
if mod(L,2)==0
Output(k+1)=1;
Output(k)=y(j);
else
Output(k+1)=1;
Output(k)=y(j);
end;
break
end;
end;
Thanks.
