Is there a memory leak in Algorithms.Rake function?

[Steverino]

I am using NI Vision 2009 with VS2008. There appears to be about an 80kb memory leak when using the Algorithms.Rake function. It gets worse if I try to use it in a separate thread. Has anyone else discovered this?

My code:

Dim lineReport As New FitLineReport

Dim returnValue As Boolean = False

Dim roi As New Roi

Dim roiCenter As New PointContour(453.5, 240)

Dim roiRotatedRect As New RotatedRectangleContour(roiCenter, 321, 478, 0)

roi.Add(roiRotatedRect)

'find straight edge

Dim rakeOptions As New EdgeOptions With rakeOptions

.ColumnProcessingMode = ColumnProcessingMode.Median

.InterpolationType = InterpolationMethod.Bilinear

.KernelSize = 37

.MinimumThreshold = 128

.Polarity = EdgePolaritySearchMode.Rising

.Width = 1

End With

Dim rakeReport As RakeReport = Algorithms.Rake(imgVwr.Image, roi, RakeDirection.RightToLeft, EdgeProcess.First, 13, rakeOptions)

Hello Steve,

There has been a similar report on this. Let me investigate this further for you.

The previous CAR was closed but it was not well documented on the workaround or any fixes. I've reopened the CAR and will get in touch with our R&D personnel.

Can you post the CAR#?

CAR#222280

The RD team is informed of this and there may be a fix in the future. The workaround for this is, since rake is looking for an edge, using SimpleEdge() instead. A way to improve execution time using Simple Edge() would be to increase the space between the Rake's.
