int OpencvSfM::ImagesGraphConnection::getHighestLink	(	int &	first_image,
		int &	second_image,
		int	max_number = 1e9
	)

get the highest link

Parameters:

first_image	[ out ] first image

bool OpencvSfM::ImagesGraphConnection::isGraphCreated

(

int

nbImages

)

[inline]

Use this function to test if the graph is already builded

Parameters:

nbImages

number of images the graph should store

Returns:

true if graph is build

void OpencvSfM::ImagesGraphConnection::orderedIdx	(	int	i1,
		int	i2,
		int	idx[2]
	)		[inline, protected]

Use this function to create an ordered image index:

Parameters:

i1	[in] first image index
i2	[in] second image index
idx	[out] index of this image link where idx[0]<idx[1]

Member Data Documentation

cv::SparseMat OpencvSfM::ImagesGraphConnection::images_graph_ [protected]

Sparse upper triangular matrix for image graph. ( i,j ) value represent the numbers of points matches between image i and j. of course ( i,j ) equal ( j,i ) so only ( i,j ) with i<j are stored.
