- <longdescription lang="en">
- Ceres Solver is a portable C++ library that allows for
- modeling and solving large complicated nonlinear least squares
- problems. It features:
- * automatic differentiation
- * robust loss functions
- * local parameterizations
- * threaded Jacobian evaluators and linear solvers
- * Levenberg-Marquardt and Dogleg (Powell, Subspace) solvers
- * Dense QR and Cholesky factorization (using Eigen) for small problems
- * Sparse Cholesky factorization (using SuiteSparse) for large sparse
- problems
- * Specialized solvers for bundle adjustment problems in computer vision
- * Iterative linear solvers for general sparse and bundle
- adjustment problems
