hello this is the code for find the connectivity but still i didnt get the answer please tell me wats the wrong

Image=imread('rice.png'); [M, N]=size(Image); Connected = zeros(M,N); Mark = []; Offsets = [-1: M; 1: -M]; Index = []; No_of_Objects = 0;

   for i= 1:M 
       for j= 1:N
            if(Image(i,j)==1)            
                 No_of_Objects = No_of_Objects +1;            
                 Index = [((j-1)*M + i)];           
                 Connected(Index)=Mark;            
                 while ~isempty(Index)                
                      Image(Index)=0;                
                      Neighbors = bsxfun(@plus, Index, Offsets');
                      Neighbors = unique(Neighbors(:));                
                      Index = Neighbors(find(Image(Neighbors)));                                
                      Connected(Index)=Mark;
                 end            
                 Mark = Mark + Difference;
            end
      end
  end
