Detailed Description

Class implementing the core of OPAL algorithm.

Class responsible for the whole OPAL algorithm. Takes a database of images and a set of options to be constructed.

Implements three main steps of OPAL:

• Constrained initialization.
• Iterative process
  1. Propagation step.
  2. Random search step.

Constructor & Destructor Documentation

OPAL()

OPAL::OPAL	(	const OPALSettings &	settings,
		const DatabaseType &	database
	)

Parameters

[in]	settings	Set of OPAL options.
[in]	database	Set of input images and their segmentations. Image to be segmented is database[0].

Member Function Documentation

ConstrainedInitialization()

void OPAL::ConstrainedInitialization

(

)

Constraint initialization.

First step of OPAL algorithm.

For each of the image located at (x, y) a random patch correspondence located at {(x',y'), t'} where t' is the index of template in the library is assigned. x' and y' are within the square initialization window around (x, y).

getFieldT()

const Image<size_t>& OPAL::getFieldT ( ) const

inline

Returns

Indexes of images in database nearest neighbors belong to.

getFieldX()

const Image<int>& OPAL::getFieldX ( ) const

inline

Returns

X-coordinate offsets between nearest neighbor patches.

getFieldY()

const Image<int>& OPAL::getFieldY ( ) const

inline

Returns

Y-coordinate offsets between nearest neighbor patches.

GetOutput()

SegType OPAL::GetOutput ( ) const

inline

Returns

The result segmentation of input image.

getSSDMap()

const Image<SSDType>& OPAL::getSSDMap ( ) const

inline

Returns

Map of SSD values between patches.

Run()

void OPAL::Run

(

)

Run OPAL algorithm.

Executes all stages successively.
