generate image of certain resolution containing black and white noise

Question

How how would i generate an image of certain resolution containing black and white noise. I want to generate a number of images with each images noise being different. Prefer if done in console of either linux or windows but coding is ok if really have to. Cheers

Answer 1

Like this with ImageMagick which is installed on most Linux distros and is available for macOS and Windows:

convert -size 512x512 xc:gray +noise random -colorspace gray noise.jpg

Replace convert with magick if using v7+ of ImageMagick.

If you mean pure black and white without shades of grey, and maybe would like a different size and a PNG format, use:

convert -size 600x400 xc:gray +noise random -colorspace gray -threshold 50% noise.png

If you want a different distribution of noise (gaussian, poisson, binomial) or to attenuate the noise, have a look at my other answer here.
