WebGray-values depend on the image format, i.e. if you have 24bit color, 8bit gray, 16bit gray or 32bit gray images, you have different ranges of values available. The mean gray-value obviously depends on the image area you are measuring. Generally the area is defined by the number of contained pixels. WebIntegrated density is pretty much area of the ROI x the mean of the ROI. So the IntDen of cytoplasm tells you how much protein is in the cytoplasm, while the mean of the cytoplasm just...

WebThe first step in calibrating the image is to measure the mean gray value of the background and the first 18 steps. We don't measure the last three steps be because they are not distinguishable and also because the calibration function in ImageJ is currently limited to 20 measurements.

WebMar 7, 2024 · I have chosen both mean gray value and integrated density to measure, but I think integrated density would be a preferable choice I agree, as “integrated density” is the thing I called “total intensity” above. But again: SUM projection, not MAX projection. Furthermore, try not to use the term “integrated density” in your scientific report.
