%description
Ceres Solver is a portable C++ library that allows for modeling and solving
large complicated nonlinear least squares problems. Features include:

  - A friendly API: build your objective function one term at a time
  - Automatic and numeric differentiation
  - Robust loss functions
  - Local parameterizations
  - Threaded Jacobian evaluators and linear solvers
  - Trust region solvers with non-monotonic steps (Levenberg-Marquardt and Dogleg (Powell & Subspace))
  - Line search solvers (L-BFGS and Nonlinear CG)
  - 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
  - Runs on Linux, Windows, Mac OS X, Android, and iOS

Notable use of Ceres Solver is for the image alignment in Google Maps and for
vehicle pose in Google Street View.
