Area Density Results and Data
Below is a definition of the Area Density Results fields and are found in the Area Density Action Tab >
Results menu button > Display Results. To display specific results, check the desired boxes in the left
column.
Area Density Results Definitions: "Density List" Tab
Region
User-defined area of interest for Area Density calculations
Total
Density
Sum total of intensities of all pixels within the region, minus the
background. Intensity is either in terms of Grey-Levels (GL) or
Optical Density (OD), depending on the Intensity Calibration
curve.
Total
Background
Sum total of intensities of all pixels within the region marked as
background. Background is calculated in two different ways.
Explanation below.
Mean
Density
Average of intensities of all pixels of the region, minus average
intensity of background pixels.
Mean
Background
Average intensity of background pixels.
Total Raw
Density
Sum total of intensities of all pixels within the region. No
background is subtracted.
Mean Raw
Density
Average intensity of intensities of all pixels within the region.
Area (Px) Total number of pixels in the region.
Minimum
Intensity
Minimum intensity value among all pixels.
Maximum
Intensity
Maximum intensity value among all pixels.
Calibrated
Value
If an Amount Calibration curve exists, this displays the calibrated
value based off that curve.
Area Density Results Property Definitions: "Statistics" Tab
Min Minimum value of attribute listed in corresponding columns, among
all regions. Region row below it provides the region for which that
value was recorded.
Max Maximum value of the attribute listed in the corresponding columns,
among all regions. Region row below it provides the region for which
that value was recorded.
Range Difference between Maximum and Minimum values, among all
