what the problem in this program to extract hiden text
s = imread('D:\desrt.jpg');
%s= getimage('D:\LSB\stegImage17.jpg');
%c = getframe(handles.axes1);
height = size(s,1);
width = size(s,2);
m = 800;
k = 1
if(k<=m)
LSB = mod(double(s(i,j)), 2);
s(i,j)=s(i,j)+LSB+b(k);
k=k+1;
end
binaryVector = b;
binValues = [ 128 64 32 16 8 4 2 1 ];
binaryVector = binaryVector(:);
if mod(length(binaryVector),8) ~= 0
error('Length of binary vector must be a multiple of 8.');
end
binMatrix = reshape(binaryVector,8,100);
display(binMatrix);
textString = char(binValues*binMatrix);
disp(textString);
