Member Function Documentation

◆ triangulate()

template<typename T >

static IndexTriangles Ocean::CV::Segmentation::Triangulation::triangulate	(	const PixelContourT< T > &	pixelContour,
		const bool	forceTriangulation = `false`,
		bool *	triangulationForced = `nullptr`
	)

static

Triangulates a given (sparse or dense) contour.

Due to performance reasons and due to irregular coordinates a sparse contours is recommended.

Parameters

pixelContour	The contour to be triangulated
forceTriangulation	True, to return a triangulation even if some of the coordinates does not allow a valid triangulation
triangulationForced	Optional resulting state whether the triangulation needed to be forced

Returns: Resulting triangulation

Template Parameters

T	The data type of the pixel contour, can be 'int' or 'unsigned int'

◆ triangulation2triangles()

template<typename T >

std::vector< Advanced::PixelTriangleT< T > > Ocean::CV::Segmentation::Triangulation::triangulation2triangles	(	const std::vector< PixelPositionT< T > > &	coordinates,
		const IndexTriangles &	triangulation
	)

inlinestatic

Converts a given set of pixel coordinates and a corresponding triangulation into triangle objects.

Parameters

coordinates	Set of pixel coordinates
triangulation	Corresponding triangulation

Returns: Resulting triangles

Template Parameters

T	The data type of the pixel coordinates, can be "int" or "unsigned int"
