Based on Intensity and MultiBlob,
this tool calculates statistical results for each ROI-polygon.
These values are measured for each
polygon:
- Intensity, min/max pixel value
- Contrast -measured between two
given percentile values
- Number of peaks in the
intensity histogram within the criteria; position, height, width
- Position, height and width for
the three highest peaks
- Flatness in the intensity
histogram
Conditions for OK or error for each polygon are as follows:
- Min/max intensity
- Min/max pixel value
- Min/max contrast
- Min/max number of peaks in histogram
- Min/max histogram peak width
- Min/max gradient/deviation
The result are given as a list of polygons; OK/error, AllOK, AllError.
The ROI-polygons may overlap and are handled independently.

| Ctrl-Z |
Set
ROI |
Sets
the selected polygon to points marked in the image. If only a single
point is marked, the polygon is moved, centered around the point.
If the tool dialog is not open, the first polygon is set. |
| Ctrl-1
- Ctrl-0 |
Set
polygon 0-10 |
Sets
the numbered polygon to points marked in the image. If only a single
point is marked, the polygon is moved, centered around the point. If
a new polygon is defined this way, any missing polygons in between
are set as empty. |
| Ctrl-Shift-1
- Ctrl-Shift-0 |
Clear
polygon 0-10 |
Clears
the numbered polygon (sets empty). |
| Ctrl-Shift-A |
Add
polygon |
This
is a shortcut to the 'Add polygon' button on the "Setup/Add
polygon" page, and is only effective when that page is visible. |
