模拟“噪音”环境——图像噪音

1、这是其中一种噪音的代艨位雅剖码：pixels = W:1024 H:1024x = from 0 to 512 Hy = from 0 to 512 Wk = mod(x+y+mod(208.0+x*3.58,13.0+mod(y*22.9, 9.0)),7.0)*0.143r = kg = kb = k说到底，就是k在起作用。

2、修改k后面的代码，就可以改变噪音的样式：k = mod(x+y+mod(0.6+x*0.36,13.0+mod(y*22.9, 9.0)),7.0)*0.143

3、如果k = mod(x+y+mod(0.6+x*0.36,13.0+mod(y*22.9, 9.0)),7.0)*0.36，得到的图形如下。

4、改变一下代码：pixels = W:1024 H:1024x = from 0 to 512 Hy = from 0 to 512 Wk = mod(x+y+mod(0.6+x*3.6,2+mod(y*36, 9.0)),7.0)*0.36r = kg =2* kb = k

5、k = mod(x+y+mod(0.6+x*3.6,2+mod(y*36, 36)),7.0)*0.36对应的图像如下。

6、换一个新的代码：pixels = W:1024 H:1024x = from 0 to 512 Hy = from 0 to 512 Wk = mod(x+y+mod(0.6+x*3.6,36+mod(y*36, 36)),7.0)*0.36r =sin(3.6*k)g =sin(2*k)b =sin(k)
