%X A new watermarking scheme by embedding a digital image signature/watermark in the wavelet domain and spatial domain is proposed.The watermark is disparted into two parts.One part is inserted in the low frequency sub-bands of wavelet domain.The other part is inserted in spatial domain directly.There are two steps in the watermark extraction.We can get the original watermark image from the two steps.This method not only has the robustness but also increase the capacity of hiding data.
