icompositor.m

一种新的ABO编码算法实现

function x=icompositor(b,y)
[m,n]=size(y);
for i=m:-1:1
    for j=n:-1:1
       if j>1;
           if b(i,j)==1;
              [y(i,j),y(i,j-1)]=changex(y(i,j),y(i,j-1));
           end
       elseif j==1 & i~=1;
           if b(i,j)==1;
              [y(i,j),y(i-1,n)]=changex(y(i,j),y(i-1,n));
           end   
       end
    end
end
x=y;
