Generate (Gaussian) white-noise image
A white-noise image is an image where all pixel values are drawn IID from a certain distribution. Here they are drawn from a Gaussian.
imnoise(x = 1, y = 1, z = 1, cc = 1, mean = 0, sd = 1, dim = NULL)
x |
width |
y |
height |
z |
depth |
cc |
spectrum |
mean |
mean pixel value (default 0) |
sd |
std. deviation of pixel values (default 1) |
dim |
dimension vector (optional, alternative to specifying x,y,z,cc) |

imnoise(100,100,cc=3) %>% plot(main="White noise in RGB") imnoise(100,100,cc=3) %>% isoblur(5) %>% plot(main="Filtered (non-white) noise") imnoise(dim=dim(boats)) #Noise image of the same size as the boats image
