[WM]: Wavelet Coefficient Selection
Hello everybody
I need to find some help in selecting wavelet coefficients for the=20 watermarking process.
I'm using Daubenches D4 decomnposition of the image.
After that i need to select some coefficicients based on a criteria.
I used mean, variance as a threshold of selecting the wavelet coefficients,= =20 but it is not giving me correct results after the
inverse DWT So kindly if any one knows any mechanism, algorithm for selecting wavelet= =20 coefficients and then getting them back
correctly.
Thanks
