摄影师的个人水印:photo by 一般表示图片的拍摄者。它是一种数字水印,数字水印过程就是向被保护的数字对象(如静止图像、视频、音频等)嵌入某些能证明版权归属或跟踪侵权行为的信息,可以是作者的序列号、公司标志、有意义的文本等等。摄影师的水印就是用来证明图片的归属,防止图片被他人盗图。在另一方面也可以提高作者其团队的知名度
In a paper to translated into English, need artificial translation.The digital multimedia data access to information provides great convenience, but also greatly improve the efficiency and accuracy of the information, but it is also very serious problems. Digital watermark is a kind of effective digital products copyright protection and data safety maintenance technology, information hiding technology is an important branch of the field.This paper mainly studied based on human visual system (HVS) digital watermarking technology. Due to the resolution and low frequency and robustness of watermarking embedding band and relevant. Comprehensive considerations, the application of the algorithm is the original image and watermark respectively by discrete wavelet transform, again will change after the watermark embedding to transform the image of the spectrum. For BMP image using human visual system, using different gezer multiplied by different weighted coefficient method to solve the visual distortion. Then from the extracted watermark image watermark. Based on the image containing watermark, this algorithm can prove that digital watermarking has high robustness.
