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
