2D Non-Rigid Tricubic Point Cloud Registration
Introduction
This repository contains a prototype implementation of a 2D non-rigid point cloud registration algorithm. The algorithm is described in the paper "Non-rigid point cloud registration using piece-wise tricubic polynomials as transformation model".

An efficient 3D implementation of this algorithm written in C++ can be found here.
Minimal example
A minimal example is provided in the test folder. It can be started with:
matlab
cd test
minimal_example
This example registers two point clouds of a fish in a non-rigid manner. The result is:

GUI
We have implemented a graphical user interface (GUI) for testing the algorithm - it can be started in the test folder with:
matlab
cd test
run_nonrigidRegistrationGUI.m
Requirements
The prototype has been tested with Matlab R2023a. It requires the "Statistics and Machine Learning Toolbox".
