I am very new to FiJi/ ImageJ but I cant seem to find a suitable answer for my problem.
I need to remove the background (or change the colour) for thousands of images. An example of the photos is below.
Currently I have tried altering the color threshold and using the wand tool to select the wing and then “Edit > Clear Outside”. However, the wing remains red and I cannot seem to get it back to the original colour.
I have also tried to automate it by making a macro that makes the selection after setting the colour threshold to an ROI and adding it to a ROI manager etc. The problem is that I think the threshold is different for each image.
I have over 2,000 images and so do not have time to do this all manually. Is there a method I can use that will automate this for me?
Any help, would be much appreciated. I don’t want to have to pay for some online tool that automatically removes background from images - surely imageJ has a way to do this? - any plugins?
Thank you all!
