Thispaper presents a robust watermarking technique for the copyright protection based
onwavelet transform (DWT) and discrete cosine
transform (DCT). In this a secrete watermark image is
embedded into a low frequency band of a cover image.
The comparison is based on statistical parameters such
as peak-signal-to-noise-ratio (PSNR), mean square
error (MSE) and normalized cross-correlation (NCC).
