Detailed Description

template<typename NUMTYPE = double, typename DATASET = CMatrixDynamic<NUMTYPE>, typename MODEL = CMatrixDynamic<NUMTYPE>>
class mrpt::math::RANSAC_Template< NUMTYPE, DATASET, MODEL >

A generic RANSAC implementation.

By default, the input "dataset" and output "model" are matrices, but this can be changed via template arguments to be any user-defined type. Define ransacDatasetSize() for your custom data types.

See RANSAC_Template::execute for more info on usage, and examples under [MRPT]/samples/math_ransac_*.

See also: mrpt::math::ModelSearch, another RANSAC implementation where models can be anything else, not only matrices, and capable of genetic algorithms.

Note: New in MRPT 2.0.2: The second and third template arguments.

An implementation of the RANSAC algorithm for robust fitting of models to data.

Parameters

data	A DxN matrix with all the observed data. D is the dimensionality of data points and N the number of points.
This	implementation is highly inspired on Peter Kovesi's MATLAB scripts (http://www.csse.uwa.edu.au/~pk).

Returns: false if no good solution can be found, true on success.

Note: [MRPT 1.5.0] verbose parameter has been removed, supersedded by COutputLogger settings.
