Detailed Description

CauchyLoss loss function used for outlier rejection.

The loss p(r) for a given residual 'r' is computed as follow: p(r) = (k^2 / 2) * log(1 + (r / k)^2), for all r

The weight w(r) for a given residual 'r' is computed as follow: w(r) = 1 / (1 + (r / k)^2) Where k Is the scaling paramter of the loss function.

Parameters
residualResidual value obtained during the optimization step.
