Vision Sensor Manual
4. Each BLOB is checked if it is fulfilling all above mentioned features/filter criteria.
5. Each BLOB fulfilling all features is a valid BLOB (green), all others are invalid (red).
Only the valid BLOBs are processed further, e.g. for data output.
Example:
If the feature "Area" is set to a range of 100 ... 150 (pixel), only BLOBs with an area within this
range are considered as valid (green).
Checkbox (Default: active)
active: feature is calculated, filtered (limits adjustable), and available for data output.
inactive: feature is calculated, but NOT filtered, but available for data output.

Additionally to the features used for filtering the BLOBs, the number of existing and valid BLOBs can be
checked.
Result positive: if number of valid (filtered) BLOBs is inside the range of "Number".
Result negative: if number of valid (filtered) BLOBs is outside the range of "Number".
If the detector counts more than 10.000 BLOBs (maximum) the detector result is negative and no further
calculations are performed.
Feature
Function
Number
Lower and upper limit of number of BLOBs accepted. (max. 10.000). If the
number of BLOBs is outside the defined limits, the detector result is
negative, although valid BLOBs are marked in green.
Invert button
With the "Invert button " (default: red/green/red) the logic of detection
can be inverted. This way the relevant range can be included or excluded.
Pipette- button (Number)
By clicking this symbol, the lower and upper limit of "Number", are set to
exactly the found number of BLOBs in the image.
Checkbox (Number, default
active)
active: feature is calculated, filtered (limits adjustable), and available for
data output.
inactive: feature is calculated, but NOT filtered, but anyway available for
data output.
