Cohen类时频方法采用不同的核函数来抑制交叉项，本质上是在模糊域对信号进行低通滤波，其中典型的方法有Choi-Williams 分布和Cone-shaped 分布等。(The Cohen time frequency method uses different kernel functions to suppress the cross term, which is essentially a low pass filter for the signal in the fuzzy domain. The typical methods are Choi-Williams distribution and Cone-shaped distribution.)

说明：  基于混合高斯模型的背景减除算法实现。matlab代码。(Gaussian mixture model-based background subtraction algorithm. matlab code.)

1. 将真彩位图转化成各色或黑白位图，进行二值化(支持多种抖动方法)处理后的位图，效果和速度极佳。 2. 将真彩或黑白位图进行 90度 , 180 度 ,270 度 高速度旋转。 (1. The true color bitmap into a colored or black and white bitmap to binary (supports multiple dithering methods) treated bitmap, effects and excellent speed. 2. The true color or black and white bitmap to 90 degrees, 180 degrees, 270-degree high-speed rotation.)

这是个由matlab仿真实现的基于dwt的数字水印技术算法，实现了数字水印的嵌入、提取和一系列攻击实验。效果良好。(This is implemented by the matlab simulation of digital watermarking technique based on dwt algorithm, realization of the digital watermark embedding, extraction and a series of attacks on experiments. Good effect.)
