Detailed Description

template<class vpTransformation>
class vpRansac< vpTransformation >

This class is a generic implementation of the Ransac algorithm. It cannot be used alone.

RANSAC is described in [15] and [19].

The code of this class is inspired by : Peter Kovesi School of Computer Science & Software Engineering The University of Western Australia pk at csse uwa edu au http://www.csse.uwa.edu.au/~pk

RANSAC - Robustly fits a model to data with the RANSAC algorithm.

Parameters
[in]npts: The number of data points.
[in]x: Data sets to which we are seeking to fit a model M. It is assumed that x is of size [d x Npts] where d is the dimensionality of the data and npts is the number of data points.
[in]s: The minimum number of samples from x required by fitting fn to fit a model. Value should be greater or equal to 4.
[in]t: The distance threshold between data point and the model used to decide whether a point is an inlier or not.
[out]M: The model having the greatest number of inliers.
[out]inliers: An array of indices of the elements of x that were the inliers for the best model.
[in]consensus: Consensus
[in]not_used: Unused parameter.
[in]maxNbumbersOfTrials: Maximum number of trials. Even if a solution is not found, the method is stopped.
[out]residual: Residual
