Static Public Member Functions

static ceres::CostFunction *	Create ()

Detailed Description

Cost function that consists of the parameter values themselves as residual.

If used with a squared loss, this corresponds to an L2 norm constraint on the parameters. This class is implemented exactly like Ceres' NormalPrior.

Constructor & Destructor Documentation

NormCost()

eos::fitting::NormCost::NormCost ( int  num_parameters )

inline

Creates a new NormCost object with set number of parameters.

Parameters

[in]

num_parameters

Number of parameters that the parameter vector contains.

Member Function Documentation

Create()

template<int num_parameters>

static ceres::CostFunction * eos::fitting::NormCost::Create ( )

inlinestatic

Factory to hide the construction of the CostFunction object from the client code.

The number of parameters is given as a template argument, so that we can use Ceres' fixed-size constructor.

operator()()

template<typename T >

bool eos::fitting::NormCost::operator() ( const T *const  x, T *  residual  ) const

inline

Cost function implementation.

Parameters

[in]	x	An array of parameters.
[in]	residual	An array of the resulting residuals.

Returns

whether the computation of the residuals was successful. Always returns true.
