Watermarking using DwtDctSvd techniques and recove
no vote
A new method for digital image watermarking which does not require
the original image for watermark detection. The watermark is added
in select coefficients with significant image energy in the transform
domain in order to ensure non-erasability of the waterrmark.
Advantages of the proposed method include: improved resistance
to attacks on the watermark, implicit visual masking utilizing
the time-frequency localization property of wavelet transform and
a robust definition for the threshold which validates the watermark.
