LocateMultipleObjects_Edges_Deprecated

Header:	AVL.h
Namespace:	avl
Module:	MatchingPro

Finds all occurrences of a predefined template on an image by comparing object edges.

Applications: Detection of multiple objects whose outlines are sharp and rigid. Often one of the first filters in a program.

Parameters

Name	Type	Range	Default	Description
inImage	const Image&			Image on which object occurrences will be searched
inSearchRegion	Optional<const Region&>		NIL	Region of possible object centers
inEdgeModel	const EdgeModel&			Model of objects to be searched
inMinPyramidLevel	int	0 - 12	0	Defines the lowest pyramid level at which object position is still refined
inMaxPyramidLevel	Optional<int>	0 - 12	3	Defines the total number of reduced resolution levels that can be used to speed up computations
inEdgeThreshold	float	0.01 -	10.0f	Minimum strength of edges used for matching with the model
inEdgePolarityMode	EdgePolarityMode::Type		MatchStrictly	Defines how edges with reversed polarity will contribute to the object score
inEdgeNoiseLevel	EdgeNoiseLevel::Type		High	Defines how much noise the objects edges have
inIgnoreBoundaryObjects	bool		False	Flag indicating whether objects crossing image boundary should be ignored or not
inMinScore	float	0.0 - 1.0	0.7f	Minimum score of object candidates accepted at each pyramid level
inMinDistance	float	0.0 -	10.0f	Minimum distance between two found objects
outObjects	Array<Object2D>&			Found objects
outObjectEdges	Optional<Array<Array<Path>>&>		NIL	Model edges of the found objects
outPyramidHeight	Optional<int&>		NIL	Highest pyramid level used to speed up computations
diagEdgePyramid	Array<Image>&			Image edges used for matching at each pyramid level
diagMatchPyramid	Array<Image>&			Candidate object locations found at each pyramid level
diagScores	Array<Array<float> >&			Scores of the found objects at each pyramid level

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outObjectEdges, outPyramidHeight.

Hardware Acceleration

This operation supports automatic parallelization for multicore and multiprocessor systems.
