SplitRegionIntoMultipleCharacters

Splits the input region into an array of regions corresponding to individual characters.

Applications: Text segmentation when the number of characters is unknown, usually followed by a RecognizeCharacters filter.

Syntax

void avl::SplitRegionIntoMultipleCharacters
(
	const avl::Region& inRegion,
	const float inProjectionSmooth,
	const int inCharacterWidth,
	atl::Array<avl::Region>& outRegions,
	atl::Array<avl::Region>& diagClasses,
	avl::Profile& diagProjection
)

Parameters

	Name	Type	Range	Default	Description
	inRegion	const Region&			Input region containing characters
	inProjectionSmooth	const float	0.0 -	1.0f	Value of smooth applied to region projection before splitting into separated characters
	inCharacterWidth	const int	0 -	15	Single character width
	outRegions	Array<Region>&			Array or regions containing single characters
	diagClasses	Array<Region>&			Regions in which characters parts will be connected into a single character region
	diagProjection	Profile&			Profile of region projection used to distinguish characters

Examples

Input region.

Result of the filter's usage.
