Parameters

image: Type: Cognex.VisionPro CogImage16Grey
The Image from which to segment lines of characters.

regions: Type: Cognex.VisionPro CogRectangleAffine
The regions of interest (ROI(s)) of the image from which to segment characters (one line of characters per region).

Return Value

Type: CogOCRMaxSegmenterResult

Exceptions

Exception	Condition
CogSecurityViolationException
CogOCRMaxSegmenterParamsException	Thrown if: any region is entirely outside the image. CharacterFramgentMaxDistanceToMainLine is less than 0.0 or greater than 1.0. CharacterFragmentMainLineMinYOverlapFrac is less than 0.0 or greater than 1.0.
NotImplementedException	Thrown if: any region is partially outside the input image.
CogTransformNotLinearException	Thrown if: the image contains a non-linear transform.
CogImageAllocatedException	Thrown if the image is not allocated.
CogTimeoutExpiredException	Thrown if the Timeout expired.
ArgumentNullException	Thrown if image is null. Thrown if regions is null.

Remarks

The regions should each contain one line of characters and surrounding featureless, but possibly nonuniform and/or noisy, background; there should be no strong features in the regions other than the one line of characters.

The regions are specified in the selected space coordinates of the input image. The x-axis should be approximately parallel to the baseline of the contained line of characters, with its positive direction pointing along the reading direction. The skew should be the approximate value of the skew of the line of characters.

If AngleHalfRange is greater than zero, the angle of the line will be refined. If SkewHalfRange is greater than zero, the skew of the line will be refined.
