I used H-watershed to segment and label fluorescently stained nuclei in a 3D image. As an output I receive a 3D image in which objects are labeled with onging numbers starting from 1. Every object has one number and every number is given only once. Then I measured the mean intensity of each object using the 3D Intensity Measure plugin. This plugin calculates mean intensities of the given objects using the original intensity image.
Now I want to select only those objects, which mean intensities are within a given range (let´s say between 100-300). I know already, which number/label these objects have.
My question: How can I tell ImageJ that it should retain only those voxels with a given value (for instance object number 3, 10 and 12) and discard all the other?
Hope this was more or less understandable.
Thanks a lot!
