Implementation and Manipulation of Fast Marching Algorithms in 2D and 3D

This tool enables manipulation of the fast marching algorithm for both 2D and 3D domains, featuring applications in shortest path extraction (including road tracking and medical image tubular structure detection), shape statistics analysis, and geodesic remeshing. The implementation utilizes efficient heap-based data structures for solving Eikonal equations and computes geodesic distances through gradient descent path extraction methods.
