Hello, I need a help. I have got a plot from a line plot profile of gray value vs mm. But I am confused what is the unit of gray value. I am getting values from 0.06 - 0.30 gray value.
if you have not calibrated the images to a defined unit, pixel values don’t have a unit. To be on the safe side, you can check in ImageJ under Analyze > Calibrate if a unit is set.
Hello all, what is the unit of gray value.
