无论如何,看来猪可能就是病毒的原始宿主。
方法通过对宿主图像和水印图像的小波变换,该算法把水印图像的低频成分嵌入到原始宿主图像的低频部分。
Methods Based on wavelet transform of watermark image and host image, low-frequency ingredient of watermark is embedded in low-frequency part of host image.
当图像(宿主信息)遭到加噪、高斯低通滤波、剪切等攻击后,其可视度、提取的水印图像与原始水印图像的类似度都是十分令人称心的;
When the image (host information) is added a noise, gaussian low-pass filter, shear attacks, the mandible, extract the original watermark image watermark image and the similarity is very satisfactory;
