#Measure intensity imagej how to

Choose Analyze > Set Measurements… and click the Area and Limit to Threshold checkboxes. To measure the area of water that you highlighted in each of the three images, select the Rectangular Selections tool in the ImageJ toolbar and drag a rectangle over just the top image of the triptych. Hit “t” as a shortcut to send the region to the ROI manager. Use one of the drawing tools to create an ROI where you want to measure. Open it in ImageJ as an image stack and go to “Analyze” “Set Measurements” to give you integrated intensity and/or mean. How does ImageJ measure intensity over time? Fluorescence is created by the absorption of energy (light) by fluorescent molecules, called fluorophores. It is the extent of emission and it depends on the concentration of the excited fluorophore. The fluorescence intensity indicates how much light (photons) is emitted.
