MAKS contains routines for pose graph optimization and rotation averaging.

• Eigen : Header-only library used for matrix operations and linear algebra solvers.
• Intel® oneAPI MKL : Free proprietary math library.

The first thing you need to know is that the MATLAB code is independent from C++. So no need to compile anything!

The C++ code depends on the Eigen library for matrix operations and Intel® oneApi MKL for the PARDISO sparse solvers and BLAS.

We provide a (hopefully) fast way of compiling everything. Just run.
source install.sh

This script will try to locate everything needed and compile the code with either icc or g++.
If you run into trouble, edit the paths for Eigen and for your installation of oneAPI MKL in the shell script.

The executable has the name ravess_example.

To run:
./ravess_example ../data/sphere_SO3.g2o

The datasets are provided as .g2o files. You will find certain datasets with a naming convention like "_SO3.g2o". These were the ones used in our ICCV paper [1]. The difference between e.g., sphere.g2o and sphere_SO3.g2o is that the latter was cleaned of repeated edges and has no vertex/node information, only edge measurements.

Some of the original datasets can be found here:
