Fiji imagej pixel count3/15/2024 ![]() Run("Set Scale. Run("Set Measurements.", "area mean shape display redirect=None decimal=3") Feel free to use and compare: Title=getTitle() I’ve amended my code according to Gabriel’s comment. Personally I will play with these lines: run("Find Maxima.", "prominence=30 strict exclude output=") Print("This image presents",number,"line intersections") Do a for loop on the "find maxima" points Print("This image features ",nResults(), '"Find Maximum"' +" points.") Run("Find Maxima.", "prominence=30 strict exclude output=List") Run("Find Maxima.", "prominence=30 strict exclude output=") Run("Analyze Particles.", "size=100-Infinity circularity=0.00-0.5 clear add") run("Analyze Particles.", "size=100-Infinity circularity=0.00-0.50 display clear add") Run("Set Measurements.", "area redirect=None decimal=1") This is what I get with this macro: macro "Counting Line Intersections" Run("Find Maxima.", "prominence=60 strict exclude output=List") Run("Find Maxima.", "prominence=60 strict exclude output=") Run("Bandpass Filter.", "filter_large=40 filter_small=3 suppress=None tolerance=10 autoscale saturate") Realized with this macro: macro "Counting Line Intersections" This is a good approximation which you may want to refine as I’ve used generic thresholding values. They are counted and total result is printed in the log. For the manual counting, we developed an ImageJ/Fiji tool that allows the user to select positive and negative cells by clicking the left and right mouse. The result table tells you how many branches and junctions you have. The second uses the ilastik software pixel classification machine learning workflow to generate a probability map image using manual user annotations for different classes of pixels in an. The second image (tagged skeletons) has all filaments in orange and, if you magnify, you’ll see the filament ends in blue and the junctions in purple. The first image, with filaments colour coded, tells you the value of the filament in the table of results. Print("I have found "+NumberOfJunctions+" junctions in "+Title) Īs end result, you get two images and a table. Run("Analyze Skeleton (2D/3D)", "prune=none show display") GetStatistics(area, mean, min, max, std, histogram) ¹This subreddit is not affiliated with the creators of ImageJ or FIJI, but is simply a place to share ideas, papers, resources, and expertise - especially as relate to questions & answers posted here.You can get a count of the junctions by skeletonising your binary image and then use the “Analyze Skeleton” function in Fiji. Sign-up for one of the mailing lists: /Mailing_Lists It also hosts a forum for interacting with the developers.įIJI Is Just ImageJ - "a distribution of ImageJ (and ImageJ2) together with Java, Java3D and a lot of plugins organized into a coherent menu structure." is full of ImageJ development and analysis resources. Image analysis is interdisciplinary, so clearly explain field-specific terms or jargon. Clearly explain what you are trying to learn, not just the method used, to avoid the XY problem.
