Description: 如何在图像中加入某一固定snr的噪声？分类:matlab与图像处理
在利用matlab做一些自己算法的抗噪分析中，常常会遇到这个问题，matlab中的加噪函数是imnoise，里面的参数是噪声的均值，方差（高斯噪声）或者是感染概率（椒盐噪声），参数不能是snr值，但是很多国外的文章的噪声分析中都是用snr值来衡量加入噪声的程度的-how the image to a fixed snr noise? Categories : Matlab and image processing using Matlab to do some of his own anti-noise algorithm analysis, will often encounter this problem, which Matlab the noise function is imnoise. inside the parameters of the noise mean and variance (Gaussian noise) or the probability of infection (Impulse Noise) Parameter values can not be snr, But many foreign article noise analysis is used to measure the value snr joined the extent of noise

Description: matlab课程设计：空间滤波增强
空域滤波就是在图像空间中借助模板对图像进行邻域操作。输出图像中每一个像素的取值都是通过模板对输入像素相应邻域内的像素值进行计算得到的。学会并掌握使用matlab进行图像的空域滤波，设计用户界面实现上述功能。。
1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的按钮，点击相应的按钮在图像界面上可以显示相应的功能。
2 首先对一副图像人为增加噪声（使用imnoise函数）；
3 对图像进行线性滤波；
4 对图像进行中值滤波；
5 对图像进行自适应滤波；
6 使用matlab自定义的滤波器进行滤波，比较各种滤波器的输出结果。

Description: J = imnoise(I,'localvar',IMAGE_INTENSITY,VAR) adds zero-mean, Gaussian
noise to an image, I, where the local variance of the noise is a
function of the image intensity values in I. IMAGE_INTENSITY and VAR
are vectors of the same size, and PLOT(IMAGE_INTENSITY,VAR) plots the
functional relationship between noise variance and image intensity.
IMAGE_INTENSITY must contain normalized intensity values ranging from 0
to 1.
