Detailed Description

This class provides functions to match two lineSegmentSet.

This class provides functions to match two lineSegmentSet. The main work is done by the descriptor members and corresponding functions in LineSegment, thus this class is strongly related to it.

Member Function Documentation

void jafar::lines::LsMatching::matchingSchemeGreyspace	(	jafar::lines::LineSegmentSet &	lsA,
		jafar::lines::LineSegmentSet &	lsB,
		jafar::lines::MatchingSet &	match,
		double	thresh
	)

Matching scheme to match to LineSegmentSet.

Matching scheme to match to LineSegmentSet with use of greyspace descriptors stored in LineSegment. The lsA is matched to lsB (imortant to know how to read the MatchingSet). To use this function you have to assign a greyspace to each LineSegment. The following steps should be done: (if you want to orient the line: LineSegment::orientLine) LineSegment::assignContourPts LineSegment::calcGreyspaceDescriptor

This function is a development version, the matching is not reliable.

Parameters:

lsA	old LineSegmentSet
lsB	new LineSegmentSet
match	storage for the matching
thresh	threshold on similarity of greyspace to accept the matching (e.g. 200), similarity of greyspaces has to be higher that that value

void jafar::lines::LsMatching::matchingSchemeHistoAndGrey	(	jafar::lines::LineSegmentSet &	lsA,
		jafar::lines::LineSegmentSet &	lsB,
		jafar::lines::MatchingSet &	match,
		double	threshHisto,
		double	threshGrey
	)

Matching scheme to match to LineSegmentSet.

Matching scheme to match to LineSegmentSet with use of greyspace descriptors stored in LineSegment and histograms. The lsA is matched to lsB (imortant to know how to read the MatchingSet). To use this function you have to assign a greyspace to each LineSegment. The following steps should be done: (if you want to orient the line: LineSegment::orientLine) LineSegment::assignContourPts LineSegment::calcGreyspaceDescriptor

The histograms have to be be extracted befor using that function as well: LineSegment:: calcHistogramDescriptor

This function is a development version, the matching is still not reliable.

Parameters:

lsA	old LineSegmentSet
lsB	new LineSegmentSet
match	storage for the matching
histoThresh	threshold on histogram difference to accept the matching (e.g. 20, depends on internal used comparison function)), histogram difference has to be smaller than that value
threshGrey	threshold on similarity of greyspace to accept the matching (e.g. 200), similarity of greyspaces has to be higher that that value

void jafar::lines::LsMatching::matchingSchemeHistoAndGreyWithPrediction	(	jafar::lines::LineSegmentSet &	lsA,
		jafar::lines::LineSegmentSet &	lsB,
		jafar::lines::MatchingSet &	match,
		double	threshHisto,
		double	threshGrey,
		double	threshA,
		double	threshMPt
	)

Matching scheme to match to LineSegmentSet.

Matching scheme to match to LineSegmentSet with use of greyspace descriptors stored in LineSegment and histograms.

Some geometric constrains are used to decrease the search range. Therfore a prediction for lsB is needed.

The lsA is matched to lsB (imortant to know how to read the MatchingSet). To use this function you have to assign a greyspace to each LineSegment. The following steps should be done: (if you want to orient the line: LineSegment::orientLine) LineSegment::assignContourPts LineSegment::calcGreyspaceDescriptor

The histograms have to be be extracted befor using that function as well: LineSegment:: calcHistogramDescriptor

This function is a development version, the matching is still not reliable.

Parameters:

lsA	old LineSegmentSet
lsB	new LineSegmentSet
match	storage for the matching
histoThresh	threshold on histogram difference to accept the matching (e.g. 20, depends on internal used comparison function)), histogram difference has to be smaller than that value
threshGrey	threshold on similarity of greyspace to accept the matching (e.g. 200), similarity of greyspaces has to be higher that that value
threshA	maximal angular difference between matched lines
threshMPt	maxmimal euklidean distance of midpoints

void jafar::lines::LsMatching::matchingSchemeHistograms	(	jafar::lines::LineSegmentSet &	lsA,
		jafar::lines::LineSegmentSet &	lsB,
		jafar::lines::MatchingSet &	match,
		double	histoThresh
	)

Matching scheme to match to LineSegmentSet.

Matching scheme to match to LineSegmentSet with use of histograms. The lsA is matched to lsB (imortant to know how to read the MatchingSet). The histograms have to be be extracted befor using that function: LineSegment:: calcHistogramDescriptor This function is a development version, the matching is not reliable.

Parameters:

lsA	old LineSegmentSet
lsB	new LineSegmentSet
match	storage for the matching
histoThresh	threshold on histogram difference to accept the matching (e.g. 20, depends on internal used comparison function)), histogram difference has to be smaller than that value

void jafar::lines::LsMatching::topologicalFilter	(	jafar::lines::LineSegmentSet &	lsA,
		jafar::lines::LineSegmentSet &	lsB,
		jafar::lines::MatchingSet &	match
	)

Reduce the matching ba applying topological constraints.

Reduce the matching ba applying topological constraints. It's still in development.
