Re: [WM]: LSB Watermarking

[Maryam Ashoori <ashoori_ma@yahoo.com>]

There are two possible classification for Watermarking methods,Spatial Domain Watermarks using spatial transforms adding
information in the image.and Transform Domain Watermarks that transform the data to the domain of one transform: FFT(Fast Fourier
Transform), DCT (Discrete Cosine Transform) or Wavelet, to introduce watermark and so the inverse of the transform yields the
final watermarked image.

Least Significant Bit Method is one of the spatial domain watermarks depends on the position of each pixel .

Hi all,

I wanto ask a very simple question.

The simple basic LSB watermarking method.... is it a SPATIAL Domain Watermarking or a FREQUENCY DOMAIN Watermarking???

Thanks a lot.
NIce day
