Texture Synthesis

[David Webster]

I am interested in generating synthetic texture image using ImageJ.
Specifically, macro textures and oriented textures. Is anyone aware of
plugins or articles to do things like this.

Hello David,

I have not done any macro/oriented textures but you may be interested in the gradient (Perlin) noise plugins that are described here:
http://www.imagingbook.com/fileadmin/en/utics/_BurgerBurgeUticsVolC_extras.pdf
This PDF is a free supplementary chapter in the follow-up volume of our book series that should be available in the next few days. The associated software is not online yet but will follow shortly.

Would it be enough to start with something like this and throw in a bunch of functions to vary ranomness of locations of peak, steepness of contrast, etc.?

  xmax = 512;
  ymax = 512;
  intmax = 127;
  xstep = 0.02;
  ystep = 0.015;
  newImage("Untitled", "8-bit Black", xmax, ymax, 1);
  for (i=0; i<ymax; i++)
    for (k=0; k<xmax; k++) {
      intensity = (intmax * sin(PI * i * ystep) * cos(PI * k * xstep)) + intmax  ;
      putPixel(k, i, intensity);
    }  // for k


Regards,

Michael

Let me try this. But, I am looking more for random arrangement of small but
visible object. e,.e,. grains of sand.
