open3d.pipelines.registration.GMLoss#
- class open3d.pipelines.registration.GMLoss#
The loss \(\rho(r)\) for a given residual
r
is:\[\begin{equation} \rho(r)= \frac{r^2/ 2}{k + r^2} \end{equation}\]The weight \(w(r)\) for a given residual
r
is given by:\[\begin{equation} w(r)= \frac{k}{\left(k + r^2\right)^2} \end{equation}\]- __init__(*args, **kwargs)#
Overloaded function.
