how to add noise to images..??

[liaw82]

Hi all,

I would like to add noise into my acquired images for my analysis purposes.. Is there a way of doing it? any noise, such as uniform white noise, gaussian white noise, also can...

thx

The attached vi do the job :

It generates a table of pseudorandom pattern (uniform or gaussian), corresponding to the size of the image, and add it to the image. Instead of converting the image to an array and back, you could probably convert the noise array to an image and add it to the original image.
