PrecisionSearchEdgeDensity Property

Applies To
Vision Objects: GeometricPlus, GeometricFusion, GeometricNeural

Description
Specifies the edge density of the image during detailed search.

Usage

    VGet  Sequence.Object.PrecisionSearchEdgeDensity, var
    VSet  Sequence.Object.PrecisionSearchEdgeDensity, value

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 property.

value

Integer value or expression for the new value of the property.

Values

• 1 - Medium
  • Vision constant: VISION_PRECISIONSEARCHEDGEDENSITY_MEDIUM
• 2 - High
  • Vision constant: VISION_PRECISIONSEARCHEDGEDENSITY_HIGH
• 3 - Very High
  • Vision constant: VISION_PRECISIONSEARCHEDGEDENSITY_VERYHIGH

Default:1 - Medium

Remarks
The PrecisionSearchEdgeDensity property adjusts the edge density of the image used during detailed search. For GeometricPlus and GeometricFusion objects, it is effective when the PrecisionSearchEnable property is set to True. For GeometricNeural objects, it is always effective. The similar DetailLevel property adjusts edge density based on contrast level, while the PrecisionSearchEdgeDensity property adjusts the amount of edges retained as representative edges after edge extraction. The Medium setting provides edge density similar to the conventional Geometric object. When set to High or Very High, the edge density increases. Increasing edge density can reduce variations in detection position, but increases processing time.
