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
