Detailed Description

This is the so called Tukey loss function which aggressively attempts to suppress large errors.

The loss p(r) for a given residual 'r' is computed as follow:

p(r) = k^2 * (1 - (1 - r / k^2)^3 ) / 2 for abs(r) <= k, p(r) = k^2 / 2 for abs(r) > k.

Parametrized Constructor.

Parameters
kIs a tunning constant for the Tukey Loss function.

◆ Weight()

double open3d::pipelines::registration::TukeyLoss::Weight ( double  residual) const
overridevirtual

The weight w(r) for a given residual 'r' is computed as follow: p(r) = (1 - (r / k)^2 )^2 for abs(r) <= k, p(r) = 0.0 for abs(r) > k. Where k Is the scaling paramter of the loss function.

Parameters
residualResidual value obtained during the optimization step.

Implements open3d::pipelines::registration::RobustKernel.
