GroupRegionsByLines

Splits an array of blobs by distance to a computed base lines

Name	Type	Range	Description
inRegions	Region Array		Input regions (parts of characters)
inRoi	Rectangle2D		Range of character classification
inRoiAlignment	CoordinateSystem2D *
inLinesCount	Integer	0 -	ROI is divided into inLinesCount lines
inLineWidth	Real	0.0 -	Value of line range used if inRemoveOutliers is set to TRUE
inRemoveOutliers	Bool		If this flag is set blobs with distance greater than inLineWidth are removed.
outLines	Region Array Array		Lines in single Array
outLine0	Region Array
outLine1	Region Array
outLine2	Region Array
outLine3	Region Array
outAlignedRoi	Rectangle2D
diagLines	Segment2D Array		Segments which indicates the position of lines
diagLineRanges	Rectangle2D Array		Rectangles represents range of lines which are included if inRemoveOutliers is set
diagRegionPoints	Point2D Array		Point which indicates region position

Examples

As you can see in the below picture, the filter's task is to divide the input region into several sub-regions by its placement in a line. As a result, each line represents a separate region.

Exemplary result of the filter's usage.
