largest contiguous area

[WASIX]

Hi there.

Say  I have an image with "spots" of different sizes. Is there a plugin that will tell me the area of the largest contiguous area?

Hello Willem,

just make a Particle Analysis in ImageJ to measure the area of all "spots":

and then summarize the results in the Results Table to get the size of the largest particle (Max):

Or do you mean a direct neighbour analysis with the largest area? Then the max particle area of the Voronoi neighbours could be calculated for each particle.

Hi there. Thanks for your answer . Makes complete sense. Should have thought of that but I'm always to hasty to post questions.
