A Novel Watermarking Scheme Based on Image Merging and DWT
摘要
Abstract
A new digital watermarking algorithm combined with image merging and stationary wavelet transform (SWT)is proposed.Unlike the common watermarking techniques,this scheme decomposes the original image A into B&C firstly,then selects one of the images B to carry on the horizontal merging and watermark is embedded in low frequency band of fusion image by using stationary wavelet transform.The final watermarked image is obtained by inverse stationary wavelet transform and horizontal split operation and synthesis with image C.Experiments show the watermarking algorithm is pro-posed in this paper not only has good fidelity,but also has good robustness to various noise attacks.关键词
