添加噪声问题
新手请教:如何往一个图象中添加一正弦噪声啊?好象matlab里只有下面几中噪声'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 nois
看来要手动加一个了,哪个高手能帮忙写一下手动添加正弦噪声的程序,或给点建议也行
