EdgeThreshold Property
EdgeThreshold Property
Applies To
Vision Objects: Edge
Description
Sets the threshold percentage for which edges with grayscale variation below this value are ignored.
Usage
VGet Sequence.Object.EdgeThreshold, var
VSet Sequence.Object.EdgeThreshold, 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 expression for the new value of the property.
Values
Integer number from 1 - 100%
Default: 2
Remarks
Use EdgeThreshold to reject edges along the search path with smaller grayscale variations. During an edge
search, the image in the search area is projected into one line of pixels. Each pixel in the projection is a
summation of all the pixels in the same column of the search area. An edge value is determined for each
pixel in the projection. The EdgeThreshold rejects edges values below the setting.
