Fixed Threshold Range
If Use In Range Value is true, then the pixels in the Fixed Threshold Range are changed to the In Range
Value before pixels in the rows or columns are averaged together. The same is done for Use Out Of Range
Value. Use In Range Value and Use Out Of Range Value can be used at the same time.
This feature can be used if the averaging in the projection can cause small high contrast features to have the
same intensity in the output image as larger, but lower contrast features. By remapping the lower contrast
pixels, high contrast features still stand out in the output image.

Blob
In the Feature Finding, Flaw Detection, and Locating Drawers
The Blob tool uses an Autothreshold or Fixed threshold method to find randomly oriented or amorphously
shaped objects within the ROI. The output list can be filtered with the Blob Filter tool to limit blobs based on
size, area, and other parameters, if desired. A Setup is available for this tool, which simplifies basic configu-
ration. Click the Setup tab to use it.
NOTE: The tool’s execution time is affected by the image resolution, a rotated tool origin, and ROIs with an
exclude area. Very high resolution images may take a long time.
In Range Value The pixel grey level value to use for the Fixed Threshold Range.
Use Out Of Range
Value
If True, pixels with a grey level within the Fixed Threshold Range are
changed to the Out Of Range Value before the average intensity is cal-
culated.
Out Of Range Value The pixel grey level value to use for the Fixed Threshold Range.
Output Name What it is
Output Image The image made from the repeated rows or columns (may be viewed on
the Output Image tab).
Input Name What it is
Input Image The image being inspected
Tool Origin The tool’s origin relative to the entire image space
Shape List The desired region of the image to search. If no shape is defined, the
entire image is processed.
