Hi,

I have an image which has ~500 blue particles and ~300 red particles. They are same in size and shape. Just spheres. But I need to know exact number of each particles.
How can I do this calculation through ImageJ? Thank you in advance.

Best,
Y

Without to see an example image, just threshold the blue or red particles and then perform a particle analysis, see:
