lsb空域水印算法，dct水印算法，dwt水印算法，处理灰度水印以及彩色图像水印，同时还有字符水印嵌入音频中。分别有着三个GUI界面实现不同功能。欢迎批评指正！(lsb airspace watermarking algorithm, dct watermarking algorithm, dwt watermarking algorithm, the watermark process grayscale and color images watermarking, as well as the characters in the watermark embedded audio. Respectively GUI interface has three different functions. Welcome criticism correction!)

进行纯净信号和加噪信号的时频域显示，及其包络图显示，并计算加噪信号的信噪比、互相关系数、峭度值，对信号进行离散余弦变换。(The time-frequency domain display of pure signal and noise-added signal and its envelope diagram display are carried out, and the signal-to-noise ratio, correlation coefficient and kurtosis value of noise-added signal are calculated.Making Discrete CoSine transform for signal)

对RGB图象的处理,一般要进行增强以达到去噪,锐化的功能,本程序在拉普拉斯算子基础上实现的(RGB images of the treatment, the general should be enhanced in order to achieve de-noising, sharpening function, the procedures in the Laplacian, based on the)
