## Classes
class | opentl::core::util::GaussNewton
| Gauss-Newton optimization. This class implements a single Gauss-Newton optimization step for nonlinear least-squares problems. For efficiency reasons, it uses cached data structures, related to the measurement size, and the number of pose degrees of freedom. More...
struct | opentl::core::util::GaussNewton::GaussNewton::GaussNewtonData_Key_dof
struct | opentl::core::util::GaussNewton::GaussNewton::GaussNewtonData_Key_dof_and_featSize
| structure for caching individual GN-terms (single features). key = pose dof (left 16bits) AND feature size (right 16bits) More...
