【摘要】 文章提出了一种基于图象纹理特征和DWT变换相结合的自适应数字水印算法,该算法利用了图象本身固有的纹理特征来寻找水印的嵌入位置,实验结果表明这种选择方法可以在降低原始图象视觉失真和经压缩变换后水印图象的失真两方面都达到较好的效果。更多还原

【Abstract】 By analyzing the characteristics of visible watermarking,an adaptive visible watermarking scheme based on texture features in wavelet transform is proposed.While embedding the watermarking into the image,the scaling factors are determined by the local luminance feature and texture features of the image.It can improve the embedding strength and the watermarking robustness.From the experimental results,the images are extremely robust to common image processing such as median filter,JPEG compression and denoising after adding the stochastic noises.更多还原
