FEATFLOW alternatives
FeatFlow (Finite Element Analysis Toolbox for Flow) is Fortran’s finite element CFD code that uses very efficient FEM sampling along with a geometric multigrid approach to solving linear systems. This results in a very fast and computationally efficient solver, which usually provides a significant or greater speedup than commercially available solvers. It can be used from MATLAB with the platform’s Multiphysics GUI.
It proposes a new end-to-end learning framework that predicts scene dense flow and platform ego movement by establishing an efficient geometric match from successive point clouds. It introduces a new scoring layer and a score-weighted loss of alignment function. Their combination effectively forces the model to learn distinctive cue point detectors and consistent function descriptors. In popular scene flow datasets (FlyingThings3D and KITTI Scene Flow), its framework vastly outperforms all modern scene flow estimation methods. On popular real-life LiDAR datasets (Oxford RobotCar and KITTI Odometry), its structure also yields pairwise scan matching results comparable to modern ones.
