(b) Find (or develop) a program to add salt-and-pepper (impulse) noise to an image. You must be able to specify the probabilities of each of the two noise components. 本实验比较简单,目的就只是往图片中添加各种噪声,比如高斯噪声或者椒盐噪声。还有一点要求就是要能够向程序指定概率等等的一些参数...
可以使用下面这个函数添加噪声 imnoise 滤波的方法请查看参考资料 J = IMNOISE(I,TYPE,...) Add noise of a given TYPE to the intensity image I. TYPE is a string that can have one of these values:'gaussian' Gaussian white noise with constant mean and variance 'localvar' Zero...
