The method you refer to is an image analysis method, not so much a method to generate noise I think. The noise in your images does look interesting but it might be a simple as mapping Blender’s basic noise texture no only to color but use it as a height map as well.
Do you have a link to the original images? (maybe we can find out what the generating method was)
Its done in c4d. The noise type is called Luka. Thats all Infos i have. I will have a look at Bryce. Here is the nearest i come with Blender sofar. Its a cloud texture with the voronoi algorithm.
It distinctly looks to me like, in the original shot, one texture is being used to modify another. For instance, a noise texture which is “sort-of being bump-mapped,” except that the pixels are being displaced in all three dimensions. It’s as though you’re using another texture to “sculpt a cloud.”
