Intensity
is a simple light-measuring tool. Use it to check light variations over time
or to calculate thresholds for blobs.
The percentile values are calculated to be used as blob tool thresholds.
Setup
Reference - Reference system selection
Search area - the tool's region of interest
- Center X, Center-Y - Center of the search area
-
dX, dY - Width and height
of the search area
The ROI is managed by the buttons -
- Paste - paste the roi from the image to the scorpion clipboard
- Copy - copies the roi to the image from the scorpion clipboard
Point & Click Clipboard Support
 The rectangular roi
is defined by four points.
One point will change the center point.

Percentile
[n]
|
The following percentiles are calculated
1,2,4,8,10,20,30,40,50,60,70,80,90,92,96,98,99

Cut
by Min
|
The percentiles
are calculated using the pixels that is in the high and low cut limit
for the histogram. Cut by Min are the number of pixels below Low cut
limit.

|
Cut
by Max
|
The percentiles
are calculated using the pixels that is in the high and low cut limit
for the histogram. Cut by Max are the number of pixels above High cut
limit.
