Light Segmentation
The Light Segmentation mode is used for extract light blobs on a dark back-
ground. This is the inverse function of the Dark Segmentation mode.
l
All pixels values to the right of the threshold function are potential blob
regions.
l
All pixels with values to left of the threshold function are background.
l
Blobs include all pixels with a value equal to the threshold value.
Inside Segmentation
The Inside Segmentation mode applies a dual-threshold function. This mode is
used to extract grey (neither dark nor light) blobs from a background con-
taining dark and light areas.
Examples:
l
The region of interest contains a grey blob on a light object or part, with
a dark image background.
l
The region of interest contains a grey blob on a dark object or part, with
a light image background.
NOTE: Inside Segmentation should always be configured using Soft Thresh-
old Functions on page 304. In most cases the Dynamic Inside on page 302
segmentation mode will provide better flexibility and better results than the
Inside Segmentation mode.
Outside Segmentation
The Outside Segmentation mode applies a dual-threshold function and is the
inverse of the Inside mode. This mode is used for extracting dark and light blobs
from a grey background.
Cases for using outside segmentation are not frequent because it is best to
analyze dark and light blobs within an image by creating two Blob Analyzer
tools: one for dark blobs and one for light blobs.
Dynamic Dark
The Dynamic Dark mode sets a percentage of the pixel distribution that is valid
for the detection of dark blobs.
This mode is similar to the Dark Segmentation on page 300 mode to which a
dynamic threshold mode is applied.
