NumOptimiseGibbsSamplingC
GibbsSampling optimiser handle class.
include	"amma/Region/NumOptimiseGibbsSampling.hh"
User Level:	Default
Library:	IPRegion
Example:	exBayesSeg.cc
Section:	Numerical Methods.Optimisation
In Scope:	std

Comments:
This is the implementation class of the GibbsSampling optimiser. The NumOptimiseGibbsSamplingC handle class should be used. The annealing schedule used is the one proposed by Geman and Geman. Please refer to Tekalp Pg.133 for explanation. This optimisation class can only be used with cost functions which have the GetGibbsSample(X, temp) function.

public NumOptimiseC

NumOptimiseGibbsSamplingC(UIntT iterations,RealT Tau,RealT minTemp,RealT beta,const ByteImageC & image)

Constructor

iterations	maximum number of iterations to use
Tau	constant
minTemp	the minimum temperature to be used during the annealing schedule
beta	the 2-pixel clique potential
image	the image over which Gibbs sampling is performed.

NumOptimiseGibbsSamplingC(const NumOptimiseGibbsSamplingC & oth)

NumOptimiseGibbsSamplingC(NumOptimiseGibbsSamplingBC & oth)

NumOptimiseGibbsSamplingC & operator=(const NumOptimiseGibbsSamplingC & cost)

Assigment of cost object.

NumOptimiseGibbsSamplingC Copy() const

Makes a deep copy

NumOptimiseC Copy() const

Makes a deep copy

NumOptimiseC & operator=(const NumOptimiseC & oth)

Assignment operator

VectorC MinimalX(const NumCostC & domain)

Do the Optimisation. Determines which X gives minimum cost function value

VectorC MaximalX(const NumCostC & domain)

Do the Optimisation. Determines which X gives maximum cost function value

const StringC GetInfo() const

Gets string describing object

const StringC GetName() const

Gets type name of the object

BooleanT Save(ostream & out) const

Writes object to stream, cna be loaded using constructor

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

BooleanT Save(ostream & out) const

Save to ostream.

RCHandleAC<NumOptimiseBC> Copy() const

Creat a deep copy of this object.
protected:

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<NumOptimiseBC> & operator=(const RCHandleC<NumOptimiseBC> & oth)

Assignment.

BooleanT operator==(const RCHandleC<NumOptimiseBC> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<NumOptimiseBC> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

NumOptimiseBC & Body()

Direct access to body.

const NumOptimiseBC & Body() const

Constant access to body.
