This is my first post in this forum. Really happy that I found this place.
I’ve been asked to do some immediate measurements on some microscopic pictures by one of my friends (Diameter, Perimeter and Area) As I had no prior experience with any image processing software, after installing Image J (Fiji), I watched some videos on youtube about it and could make my way through setting the scale and some other rudimentary settings.
But here are my 2 questions, they may seem pretty basic for you, but I’ve been searching for the answers like hours!
As you see in these samples pictures, I’m been asked to measure the perimeter, area, and diameters of the cell and nucleus, exactly like these pictures.
Question1: For selecting the perimeter of the cell or nucleus, is there an automatic magic wand like the tool in Photoshop? or should I draw the perimeter manually using freehand selector?
Question2: How can I transfer and show the measurements into the white boxes, like shown in the pictures?
I would be really grateful if you help me.
PS: By the way, please ignore the scale bar in the pictures, I didn’t draw them (actually the pics are samples that I found from another place) and using pixels as units, they don’t seem correct.
