Mean gray value vs integrated density
WebMay 25, 2012 · Accepted Answer. Yes, as a generality, images can contain pixels with negative values. If I recall correctly, if you look at the diagrams of color representation as perceived by the human eye, and you look at how they define RGB coordinates, then there are some colors that humans can perceive that would have to be modeled as negative … WebCalculation of Corrected Integrated Density (i.e. the value you want - total fluorescence per cell).

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. Webthe optical density of the elastic fibers, the gray value threshold was determined manually for each image to distinguish the particles (that is, the areas with gray values within the threshold range) from the background. The micrometer-to-pixel scale was calculated from the scale generated by CellSens® when each image was obtained.
WebMar 22, 2024 · Mean filter: the pixel is replaced with the average of itself and its neighbors within the specified radius. The menu item Process › Smooth is a 3×3 mean filter. Gaussian filter: This is similar to a smoothing filter but instead replaces the pixel value with a value proportional to a normal distribution of its neighbors.
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.
