I’m an amateur algae cultivator and newbie to cellprofiler. The image is of chlorella vulgaris on a hemocytometer. I’d like to automate cell counting. However, I’ve not been able to locate a tutorial on this. A related topic has a broken link to https://cellprofiler.org/examples.htm
In general, you would need to detect the grids and use them to see how many cells you have in each. The grid location is important, so If you want to use the same pipeline moving forward you would need to make sure to have similar grid locations.
Hope this helps!
