5.1.1 Profile Settings Panel
Sample detection
This panel offers options for threshold setting and selection of the area to be scanned.
•
Source:
Brightfield preview – a normal type of illumination in the microscope for scanning the
slide. This option is recommended when scanning in Brightfield mode.
•
Thresholding:
The manually specified value is used for thresholding during scanning. Preview
image of the loaded slide is displayed in the Preview window, and when modifying any of the
parameter values, it will have effect on the preview image. If the threshold value presented
on the Microscope Controller preview window is modified, this value is automatically applied
by the profile in the Profile Settings panel.
◦
Specimen threshold
This value is definable manually:
This sets the sensitivity of the specimen detection. To
set the desired threshold value manually, change the setting in the
Specimen threshold
level
selection box in the range of 0-255. The default value is 220. Smaller values result in
a more sensitive scanning, meaning that more areas will be digitized, however, this may
also include specks or other imperfections of the slide. Greater values result in a less
sensitive scanning, but it is possible that some of the smaller specimen areas will not be
digitized.
◦
Auto Threshold
By clicking
the specimen will automatically be detected in the preview image.
Caution!
Make sure that the detection result is acceptable for you. Otherwise, set the
threshold value manually or append missing areas with the help of
appropriate functions in the
Preview
window.
