CogPatInspectPattern.SobelOffset Property

CogPatInspectPattern SobelOffset Property

Cognex VisionPro 9.7

The Sobel coefficients are used to compute a pseudo standard deviation image when the pattern has been trained from a single image. Standard Deviation Pixel = [SobelScale * Sobel Magnitude Pixel Value] + SobelOffset.

Event Type

Reason

CogPatInspectPattern Changed

Fires when the Sobel offset changes.

The following state flag may be affected:

SfSobelOffset

CogPatInspectPattern Changed

Fires when the Sobel offset changes and the trained threshold image is updated as well.

The following state flags may be affected:

Remarks

The currently trained threshold image is updated when the Sobel offset value is changed and the pattern has been trained from a single image.

Default Value: 0.0
