const

Fits a line to the given set using the Least Median Squares method. In contrast to the official LMS, we extensively sample lines if the combinatorial effort is less than num sets.

Returns

The best fitting line.

double rdf::LineFitting::medianResiduals ( const QVector< Vector2D > &  pts, const Line &  line  ) const

protected

Returns the median of the squared distances between pts and the line.

Parameters

pts	The point set.
line	The current fitting line.

Returns

The median squared distance.

void rdf::LineFitting::sample ( const QVector< Vector2D > &  pts, QVector< Vector2D > &  set, int  setSize = 2  ) const

protected

Returns randomly sampled pts.

Parameters

pts	Input points.
set	A randomly sampled set of size setSize.
setSize	The set size returned.
