| Summary: | This paper proposes a robust digital image
watermarking techniques by using discrete wavelet transform.
The watermark is embedded in 2-level diagonal coefficient to
achieve high performance in term of imperceptibility. The
watermark is embedded by selecting a seed that generating
pseudorandom noise sequence. Then the Watermark is
extracted back by using the same pseudorandom noise
sequence seed in the embedding. The experimental results
show that the proposed algorithm provides good level of
imperceptibility. Moreover, the watermarked image is robust
against several attacks. |
