水印嵌入对数字图像压缩的影响

Effect of Embedding Watermark on Compression of the Digital Images

Deepak Aggarwal, Kanwalvir Singh Dhindsa

摘要:

图像压缩在图像处理中起着非常重要的作用,特别是当我们要将图像通过网络传输时。互联网上的信息面临的威胁越来越大,图像也不例外。通常,图像作为压缩图像在互联网上发送,以最佳地使用网络带宽。但是,由于我们在网络上,在任何中间级别,图像都可以有意或无意地改变。为了确保正确的图像被传递到另一端,我们将水印嵌入图像。然后将水印图像压缩并在网络上发送。当图像在另一端解压缩时,我们可以提取水印,并确保图像与另一端发送的图像相同。虽然水印的图像增加了未压缩的图像的大小,但必须做到这一点,以实现高度的鲁棒性,即图像如何承受对它的攻击。本文是一种尝试,使传输的图像安全的中间攻击,通过应用通常使用的压缩变换。

英文摘要:

Image Compression plays a very important role in image processing especially when we are to send the image on the internet. The threat to the information on the internet increases and image is no exception. Generally the image is sent on the internet as the compressed image to optimally use the bandwidth of the network. But as we are on the network, at any intermediate level the image can be changed intentionally or unintentionally. To make sure that the correct image is being delivered at the other end we embed the water mark to the image. The watermarked image is then compressed and sent on the network. When the image is decompressed at the other end we can extract the watermark and make sure that the image is the same that was sent by the other end. Though watermarking the image increases the size of the uncompressed image but that has to done to achieve the high degree of robustness i.e. how an image sustains the attacks on it. The present paper is an attempt to make transmission of the images secure from the intermediate attacks by applying the generally used compression transforms.
