In this survey, we first describe the purposes for image hiding.
They are Steganography, Image Watermarking and Image
Authentication. Classified by hiding methods, image hiding can
be divided into pixel-based image hiding, frequency-based image
hiding and VQ-based image hiding. In the aspect of pixel-based
image hiding, we describe three representative methods, the
substitution table technique, the modulus function technique, and
the LSB matching revisited technique. As for frequency-based
and VQ-based image hiding, we introduce methods to do
Steganography, Image Watermarking and Image Authentication
by applying image compression methods, JPEG and Vector
Quantization.
