詳解

Levenberg-Marquardt solver. Starting with the specified vector of parameters it optimizes the target vector criteria "err" (finds local minima of each target vector component absolute value).

When needed, it calls user-provided callback.

関数詳解

create()

static Ptr< LMSolver > cv::LMSolver::create ( const Ptr< LMSolver::Callback > &  cb, int  maxIters  )

static

Creates Levenberg-Marquard solver

引数

cb	callback
maxIters	maximum number of iterations that can be further modified using setMaxIters() method.

getMaxIters()

virtual int cv::LMSolver::getMaxIters ( ) const

pure virtual

Retrieves the current maximum number of iterations

run()

virtual int cv::LMSolver::run ( InputOutputArray  param ) const

pure virtual

Runs Levenberg-Marquardt algorithm using the passed vector of parameters as the start point. The final vector of parameters (whether the algorithm converged or not) is stored at the same vector. The method returns the number of iterations used. If it's equal to the previously specified maxIters, there is a big chance the algorithm did not converge.

引数

param

initial/final vector of parameters.

Note that the dimensionality of parameter space is defined by the size of param vector, and the dimensionality of optimized criteria is defined by the size of err vector computed by the callback.

setMaxIters()

virtual void cv::LMSolver::setMaxIters ( int  maxIters )

pure virtual

Sets the maximum number of iterations

引数

maxIters

the number of iterations
