“…Digital watermarking methods are mainly used in healthcare [25], remote sensing [22] and industrial [18,24] application areas for the purpose of ownership identification [30], copyright protection [49], fingerprinting [32,33,36], monitoring [10,19,20] and forgery detection [12]. With respect to the watermark embedding domain digital watermarking methods like steganography [26,27,29,35] can be generally classified as spatial domain methods and transform domain methods such as discrete Fourier transform [34], discrete cosine transform [1,3,23], discrete wavelet transform [2,17,21,41,42].…”
