Member Function Documentation

bool lti::polygonApproximation::apply	(	const borderPoints &	src,
		const pointList &	forcedVertices,
		polygonPoints &	dest
	)			const

Approximate the given border points as a polygon, ensuring that the points in the given point list are inserted as vertices.

This point list must fulfill followint two conditions:

1. It must have the same sequence than theBorderPoints.
2. The points must be contained by the theBorderPoints

At the end of the approximation process the polygon-points-list contains the coordinates of the vertices.

Parameters:

	src	border points with the contour to be approximated
	forcedVertices	list of vertices that must be included in the polygon representation. This list must be a subset and respect the same ordering as in theBorderPoints
	dest	polygon approximation of the contour.

Returns:

true if apply successful or false otherwise.

bool lti::polygonApproximation::apply	(	const borderPoints &	src,
		polygonPoints &	dest
	)			const

Approximate the given border points as a polygon.

At the end of the approximation process the polygon-points-list contains the coordinates of the vertices.

Parameters:

	src	border points with the contour that must be approximated
	dest	polygon approximation of the contour.

Returns:

true if apply successful or false otherwise.
