class  gtsam::noiseModel::Base
 noiseModel::Base is the abstract base class for all noise models. More...
class  gtsam::noiseModel::Gaussian
 Gaussian implements the mathematical model |R*x|^2 = |y|^2 with R'*R=inv(Sigma) where y = whiten(x) = R*x x = unwhiten(x) = inv(R)*y as indeed |y|^2 = y'*y = x'*R'*R*x Various derived classes are available that are more efficient. More...
class  gtsam::noiseModel::Diagonal
 A diagonal noise model implements a diagonal covariance matrix, with the elements of the diagonal specified in a Vector. More...
class  gtsam::noiseModel::Constrained
 A Constrained constrained model is a specialization of Diagonal which allows some or all of the sigmas to be zero, forcing the error to be zero there. More...
class  gtsam::noiseModel::Isotropic
 An isotropic noise model corresponds to a scaled diagonal covariance To construct, use one of the static methods. More...
class  gtsam::noiseModel::Unit
 Unit: i.i.d. More...
class  gtsam::noiseModel::Robust
 Base class for robust error models The robust M-estimators above simply tell us how to re-weight the residual, and are isotropic kernels, in that they do not allow for correlated noise. More...
