ParticleDiscrimination Method
Syntax
CWIMAQVision.ParticleDiscrimination SourceImage, DiscriminationData, ParticlesReport
Return Type
On success, this method returns 0. On failure, this method returns a negative number.
Purpose
Obsolete—Use SelectParticles instead. Filters an array of particle reports based on criteria ranges. Call the Particle method before calling this method.
Remarks
Use this method with U8 images.
This method does not modify the image. ParticleDiscrimination works only on the particle report array, removing particle reports that do not match the selection criteria.
Parameters
SourceImage As CWIMAQImage
The image previously used in CWIMAQVision.Particle. The function needs this image to get the calibration values.
DiscriminationData As CWIMAQDiscriminationData
A report that describes the criteria for the particles you want to keep.
Only the particles with a parameter matching the ranges given by the report elements are not removed from ParticlesReport.
ParticlesReport As CWIMAQFullParticleReport
A CWIMAQFullParticleReport object containing the particles reports from Particle . The report is processed and returned with only the matching particle elements.
Example
Private Sub Run_Click()
Dim report1 As New CWIMAQFullParticleReport
Dim report2 As New CWIMAQDiscriminationData
'Generate Particle Report
CWIMAQVision1.Particle CWIMAQViewer1.Image, report1
' Filter the report so that it only contains particles with an
' area between 100 and 200 pixels
report2.Count = 1 ' Discriminate one parameter
report2.Parameter(1) = cwimaqParticleArea ' Discriminate area
report2.MaxValue(1) = 200 ' 200 is the max area
report2.MinValue(1) = 100 ' 100 is the min area
CWIMAQVision1.ParticleDiscrimination CWIMAQViewer1.Image, report2, report1 ' Filter report1 report
