Hi all, There are some images that I obtained from different levels. Like in file. Four of them have different level particles inside it. How can I define the appropriate value. Is it necessary to remove information zone from image or not? For each image ı want to define suitable value. Also there should be similar images like this Thanks.

Any suggestion. For example triangle threshold or look for histogram values. Or looking for two level segmentation which one is better?

If I try random values for all images for example 0.5 for 1 and 4 image. And 0.7 for 2 and 3 image I got good results. But for all of them if i use graythresh then theresult not good for me. So any suggestions.
