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-mean Gaussian white noise
with an intensity-dependent variance
'poisson' Poisson noise
'salt & pepper' "On and Off" pixels
'speckle' Multiplicative noise
Depending on TYPE, you can specify additional parameters to IMNOISE. All
numerical parameters are normalized; they correspond to operations with
images with intensities ranging from 0 to 1.

噪声是指音高和音强变化混乱、听起来不谐和的声音。是由发音体不规则的振动产生的,从物理学的角度来看:噪声是发声体做无规则振动时发出的声音,在一定环境中不应有而有的声音。泛指嘈杂、刺耳的声音。从环境保护的角度看:凡是妨碍到人们正常休息、学习和工...
