Member Function Documentation

void kjb::Line_segment_set::add_segment ( const Line_segment &  isegment )

inline

Adds a line segment to this collection.

kjb::Edge_set * Line_segment_set::convert_to_edge_set	(	unsigned int	num_rows,
		unsigned int	num_cols
	)

void Line_segment_set::draw	(	kjb::Image &	img,
		double	ir,
		double	ig,
		double	ib,
		double	width = 1.0
	)		const

Draws this line segment set.

Draws the line segment on an image

Parameters

img	the image
ir	the red channel
ig	the green channel
ib	the blue channel
width	the width of the segment to be drawn (in pixel)

const Line_segment& kjb::Line_segment_set::get_segment ( unsigned int  i ) const

inline

returns the ith fitted line segment

const std::vector<Line_segment>& kjb::Line_segment_set::get_segments ( )

inline

Returns a vector containing the fitted line segments.

Line_segment_set& kjb::Line_segment_set::operator= ( const Line_segment_set &  iseg )

inline

void Line_segment_set::randomly_color	(	kjb::Image &	img,
		double	width = 1.0
	)		const

Randomly colors this line segment set on an image.

Draws the line segment set using a different random color for each segment

Parameters

img	the image
width	the width of the segment to be drawn (in pixel)

void Line_segment_set::read ( std::istream &  in )

virtual

Reads this Edge_segment_set from an input stream.

Read an edge segment set from an input stream. The input edge_set is necessary to bind the fitted segments to the original detected edges

Parameters

edge_set	set of edges fitted to the line segments to be read
in	the input stream to read this edge segment set from

Implements kjb::Readable.

void kjb::Line_segment_set::read ( const char *  fname )

inlinevirtual

Reads this Edge_segment_set from an input file.

Reimplemented from kjb::Readable.

void Line_segment_set::remove_frame_segments	(	unsigned int	num_rows,
		unsigned int	num_cols
	)

unsigned int kjb::Line_segment_set::size ( ) const

inline

Returns the number of segments in this set.

void Line_segment_set::write ( std::ostream &  out ) const

virtual

Writes this Edge_segment_set to an output stream.

Implements kjb::Writeable.

void kjb::Line_segment_set::write ( const char *  fname ) const

inlinevirtual

Writes this Edge_segment_set to a file.

Reimplemented from kjb::Writeable.
