Analyzing images by color


The image I’m analyzing contains dendritic cells(red) and t cells(green).
I’m trying to gather information about it.
How do I use imagej to gather information about my picture (like the number of green cells surrounding the red ones)


Dear @lefthandjj,

please take a look at the following page/presentation for an introduction into segmentation (i.e. object detection):

If you have practical questions, please get back to us with them.




Thank you very much for your help.

I looked into segmentation and tried a few out. I have pictures with T cells and dendritic cells, and the T cells gather around the DCs. I am trying to gather data about T cells in the vicinity of the DCs. Is there any plugin/feature that allows me to analyze the T cells in a certain sized region around the DCs?
