| Area |
Area of a WPB object in μm2. |
| Mean |
Average grey intensity of a WPB object [relative fluorescence unit r.f.u.] |
| StdDev |
Standard deviation of a WPB object pixel intensity [r.f.u.]. |
| Min |
Minimum intensity of a WPB object [r.f.u.]. |
| Max |

Median grey intensity of a WPB object [r.f.u.]. |
| RawIntDen |
The sum of the values of the pixels in a WPB [r.f.u.]. |
| Slice |
The number of image in an image stack. |
| FeretX |
The X coordinate of the end of a WPB’s Feret diameter [pixel]. |
| FeretY |
The Y coordinate of the end of a WPB’s Feret diameter [pixel]. |
| FeretAngle |
Angle between the horizontal axis of the image and the Feret’s diameter of a WPB object [degree]. |
| MinFeret |
The shortest diameter between any two points along a WPB’s boundary [μm]. |
| AR |
Aspect ratio is a shape descriptor of a WPB, means the ratio of the length of the primary and secondary axes of a WPB’s fitted ellipse. |
| Round |
Roundness is a shape descriptor of a WPB, the inverse of AR. |
| Solidity |
The ratio between a WPB’s area and convex area. |
