Hi guys,
I'm having a difficult time to calculate the area fraction of the particles. The normal method did not work very well on my case due to lots of noise on the background. Despeckle does not help much. I've attached one image. Can anyone help me? Thanks! Shirley |

Hi Priyanka,
I'm trying to calculate the area fraction of the black particles with enclosed shape. (so the very black particles on the image. Some of them are just black dots; some of them have irregular shapes). Thanks for your reply :) |

Hi Shirley,
The Weka segmentation plugin seems to yield good results. Otherwise a laplacian operation of sigma=3, followed by a threshold is also working quite well.
