Detailed Description

Homotopy preserving Skeleton.

This class implements the algorithm of Ji and Piper (IEEE Transactions on Pattern Analysis and Maschine Intelligence, vol. 14, no. 6, june 1992).

The generated skeletons will keep the original homotopy of the input channel.

The input data must be segmented, with values 0 (background) and not 0 (object).

Member Function Documentation

channel8& lti::skeleton::apply	(	const channel8 &	src,
		channel8 &	dest
	)			const

operates on a copy of the given parameters.

Parameters:

	src	channel8 with the source data.
	dest	channel8 where the result will be left.

Returns:

a reference to the dest.

channel& lti::skeleton::apply	(	const channel &	src,
		channel &	dest
	)			const

operates on a copy of the given parameters.

Parameters:

	src	channel with the source data.
	dest	channel where the result will be left.

Returns:

a reference to the dest.

channel8& lti::skeleton::apply

(

channel8 &

srcdest

)

const

operates on the given parameter.

Parameters:

srcdest

channel8 with the source data. The result will be left here too.

Returns:

a reference to the srcdest.

channel& lti::skeleton::apply

(

channel &

srcdest

)

const

operates on the given parameter.

Parameters:

srcdest

channel with the source data. The result will be left here too.

Returns:

a reference to the srcdest.

channel8& lti::skeleton::calc_jpoints	(	const channel8 &	src,
		const channel8 &	match,
		channel8 &	dest
	)			const [protected]

calculate the jpoints for every pixel in src jpoints are needed to preserve homotopy

virtual functor* lti::skeleton::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::functor.

skeleton& lti::skeleton::copy

(

const skeleton &

other

)

copy data of "other" functor.

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::functor.

channel8& lti::skeleton::difference	(	const channel8 &	img,
		const channel8 &	stamp,
		channel8 &	dest
	)			const [protected]

returns img \ stamp.

(img with all pixels of stamp left out)

const parameters& lti::skeleton::getParameters

(

)

const

returns used parameters

Reimplemented from lti::transform.

virtual const char* lti::skeleton::getTypeName

(

)

const [virtual]

returns the name of this type ("skeleton")

Reimplemented from lti::transform.

channel8& lti::skeleton::img_or	(	const channel8 &	src1,
		channel8 &	srcdest
	)			const [protected]

provides logical or of two channel8s

channel8& lti::skeleton::visualize	(	channel8 &	srcdest,
		const int &	val
	)			const [protected]

sets all non-zero values of a channel to int val
