Detailed Description

Segmentation class to represent a section of the LV myocardium.

Structure to save the segmentation of a section of the myocardium. In theory this can be used for any king of segmentation that uses a polynom to approximate a segmented 2D shape.

Constructor & Destructor Documentation

CSegSection() [1/3]

CSegSection::CSegSection

(

)

default constructor

CSegSection() [2/3]

CSegSection::CSegSection	(	const std::string &	id,
		const Points &	points,
		bool	is_open
	)

Constructor to create a segmentation shape and naming it

Parameters

id	ID of the section (and color identifier)
points	the points that define a closed polynom representing the shape
is_open	describes if points should be interpreted as polygon (i.e. the last point connects to the first), or as poly-line only.

CSegSection() [3/3]

CSegSection::CSegSection	(	const CXMLElement &	node,
		int	version
	)

Constructor to create a segmentation shape based on a XML sub tree

Parameters

node	root of the XML sub tree
version	segmentation set version the node stems from.

Member Function Documentation

append_to()

void CSegSection::append_to

(

C2DPolygon &

polygon

)

const

Append this shape to another shape, a very crude version of a logical or

Parameters

polygon

to add the shape to

draw()

void CSegSection::draw	(	C2DUBImage &	output,
		unsigned char	color
	)		const

Draw the shape to a 2D image with a given color

Parameters

output	image to draw to
color	color to use

draw_xor()

void CSegSection::draw_xor

(

C2DUBImage &

output

)

const

Draw the binary shape to a 2D image by xor-ing with what is already in there

Parameters

output

image to draw to

get_boundingbox()

const C2DBoundingBox CSegSection::get_boundingbox

(

)

const

Returns

the orthogonal bounding box enclosing the shape

get_hausdorff_distance()

float CSegSection::get_hausdorff_distance

(

const CSegSection &

other

)

const

Evaluate the Hausdorff distance between this shape and another one

Parameters

other

Returns

the Hausdorff distance

get_id()

const std::string& CSegSection::get_id

(

)

const

Returns

the ID of the section

get_points()

const Points& CSegSection::get_points

(

)

const

Returns

the list of the points defining the section shape

inv_transform()

void CSegSection::inv_transform

(

const C2DTransformation &

t

)

transform the shape by transforming its individual points

Parameters

t	the inverse of the transformation to be applied

is_open()

bool CSegSection::is_open

(

)

const

Returns

whether the curve is open (true) or closed (false).

shift()

void CSegSection::shift

(

const C2DFVector &

delta

)

translate the segmentation by a given shift

Parameters

delta

transform()

void CSegSection::transform

(

const C2DTransformation &

t

)

transform the shape by transforming its individual points

Parameters

t	the transformation to be applied

write()

void CSegSection::write	(	CXMLElement &	node,
		int	version
	)		const

Store the segmented section into a XML sub-tree

Parameters

node	parent node to which the subtree should be added
version	segmentation set version the node stems from.
