提出了一种基于小波域的图像数字水印算法・该算法将相互正交的两种水印(鲁棒水印和参考 水印)同时添加到经过DWT后的载体图像小波系数中,然后用小波反变换得到添加了水印的图像・用提取出 的参考水印来估计图像所受到的攻击,由于提取出的鲁棒水印所受的攻击与参考水印受到的攻击一样,因此 可以估计出原始的鲁棒水印・通过对嵌入水印的图像进行加入噪声、滤波、压缩以及裁剪等大量图像处理等试 验,均能正确检测出水印,表明该算法具有很好的感知效果和鲁棒性 -A wavelet-based image digital watermarking algorithm that the algorithm will be mutually orthogonal two watermarks (watermark robust watermarking and reference) at the same time added to the carrier after image after DWT wavelet coefficients, and then using wavelet transform has been Add a watermark image to use to extract a reference to estimate the watermark image by the attacks, as a result of the robust watermark extracted suffered attacks and the reference watermark by the same attack, it can be estimated through the original Robust Watermarking of the embedded watermark image by adding noise, filtering, compression and cutting, such as a large number of image processing such as testing, can correctly detect the watermark, show that the algorithm has good

函数信号发生器根据用途不同，有产生三种或多种波形的函数发生器，其电路中使用的器件可以是分离器件，也可以是集成器件，产生方波、正弦波、三角波的方案有多种，如先产生正弦波，根据周期性的非正弦波与正弦波所呈的某种确定的函数关系，再通过整形电路将正弦波转化为方波，经过积分电路后将其变为三角波。-Function Generator according to different purposes, there have three or more of the waveform function generator, a device used in the circuit can be separate devices, can also be integrated device, resulting in square wave, sine wave, triangle wave of the program how species, such as created in the first sine wave, according to the periodic non-sine wave and sine wave which was a function of a certain set, and then by the sine-wave shaping circuit into a square wave, after integrating circuit will turn it into a triangle wave.
