Applies To

Description

Returns the number of features found within a single Search Window for a Blob, Correlation, Edge, or
Geometric object.

Usage

VGet Sequence.Object.NumberFound, var

Sequence Name of a sequence or string variable containing a sequence name.

Object

Name of an object or string variable containing an object name. The object must exist in the
specified sequence.

var

Integer variable that will contain the value of the result.

Values

Valid number found for all objects is 0 - 100.

Remarks

Blob, Correlation, Edge, and Geometric objects support the finding of multiple features within a single
Search Window. The NumberToFind property defines how many features to search for.

The NumberFound result returns how may features were actually found.

The NumberFound result is a special result. It will always return the number of features that were found
for the specified vision object regardless of the setting of the CurrentResult property. All the other results
in the Results List are specific to each individual results record and will have different values depending
upon the setting of the CurrentResult property.

Blob results are ordered by largest found blob to smallest found blob. (i.e. result record 1 (CurrentResult =
1) contains the results for the largest blob.)

Correlation results are ordered by highest Score result to lowest Score result. (i.e. result Record 1
(CurrentResult =1) contains the results for the feature with the highest score.)
