SVD-based-watermarking
基于SVD的DCT域和DWT域的经典水印算法,该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵,鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors.

小波边缘检测
说明: 数学地角度来看,信号与图像处理可以统一看作是信号处理(图像可以看作是二维信号),在小波分析地许多分析的许多应用中,都可以归结为信号处理问题。对于其性质随时间是稳定不变的信号,处理的理想工具仍然是傅立叶分析。但是在实际应用中的绝大多数信号是非稳定的,而特别适用于非稳定信号的工具就是小波分析。(Mathematically, signal and image processing can be regarded as signal processing (image can be regarded as two-dimensional signal). In many applications of wavelet analysis, they can be reduced to signal processing. For signals whose properties are stable over time, the ideal tool for processing is still Fourier analysis. However, most of the signals in practical applications are unstable, and the tool especially suitable for unstable signals is wavelet analysis.)

Average-model
用平均背景法去除背景,算法思想比混合高斯模型和codebook模型简单,适合提取背景变化较小的场景。用中值滤波去除掉产生的椒盐噪声(Average method to remove the background with the background, the algorithm thought codebook than the Gaussian mixture model and a simple model for extraction of small changes in background scene. With a median filter to remove salt and pepper noise generated)

自写M函数,做灰度图像的灰度级数及灰度范围的自定义设置。例如:将[0 255]的uint8图像变换成8级灰度的灰度范围为[0 7]图像或者[11.5 25.8]图像。
输出图像为double类,用户可将图像归一化后自行转换为所需类型。(This is a M function written by self, it can be used to rebuild a image with a given number of gray-level and a given gray-scale.
Output image is double class.)
