Detailed Description

HuberLoss loss function used for outlier rejection.

The loss p(r) for a given residual 'r' is computed as follow: p(r) = r^2 for abs(r) <= k, p(r) = k^2 * (abs(r) - k/2) for abs(r) > k

HuberLoss()

cloudViewer::pipelines::registration::HuberLoss::HuberLoss ( double  k )

inlineexplicit

Parametrized Constructor.

Parameters

k	Is the scaling paramter of the huber loss function. 'k' corresponds to 'delta' on this page: http://en.wikipedia.org/wiki/Huber_Loss_Function

Weight()

double cloudViewer::pipelines::registration::HuberLoss::Weight ( double  residual ) const

overridevirtual

The weight w(r) for a given residual 'r' is computed as follow: w(r) = 1.0 for abs(r) <= k, w(r) = k / abs(r) for abs(r) > k Where k Is the scaling paramter of the loss function.

Parameters

residual

Residual value obtained during the optimization step.
