I'm trying to apply an steganography LSB code that is got here.
How do I solve this?
I try:
function output = bitcmpOld(x,N)
if nargin < 2
output = bitcmp(x);
else
maxN = 2^N-1; % This is the max number you can represent in 4 bits
fmt = 'uint8'; % You can change uint8 to uint16 or 32
out1 = eval(['bitcmp(',fmt,'(x)',',''',fmt,''')']);
out2 = eval(['bitcmp(',fmt,'(maxN)',',''',fmt,''')']);
output = out1 - out2;
end
end
But don't work.
