Using airborne and terrestrial LiDAR data from glaciers in Greenland and Antarctica, we compare three change detection methods for accuracy and performance. We focus in particular on one method, Coherent Point Drift (CPD). We find that CPD outperforms Iterative Closest Point (ICP) and Particle Imagi...
