Protected Member Functions inherited from cv::Algorithm | |
void | writeFormat (FileStorage &fs) const |
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.
|
static |
Creates Levenberg-Marquard solver
cb | callback |
maxIters | maximum number of iterations that can be further modified using setMaxIters() method. |
|
pure virtual |
Retrieves the current maximum number of iterations
|
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.
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.
|
pure virtual |
Sets the maximum number of iterations
maxIters | the number of iterations |
