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 [13] and [15].

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

npts	: The number of data points.
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.
s	: The minimum number of samples from x required by fitting fn to fit a model. Value should be greater or equal to 4.
t	: The distance threshold between data point and the model used to decide whether a point is an inlier or not.
M	: The model having the greatest number of inliers.
inliers	: An array of indices of the elements of x that were the inliers for the best model.
consensus	: Consensus
not_used	: Unused parameter.
maxNbumbersOfTrials	: Maximum number of trials. Even if a solution is not found, the method is stopped.
