Coherent Point Drift (CPD) is a point-set registration algorithm, originally developed by Andriy Myronenko et al. This is a C++ library that runs CPD.CPD can be compared to Iterative Closest Point, another point-set registration algorithm that is widely used. While ICP minimizes point-to-...
Pure Numpy Implementation of the Coherent Point Drift Algorithm. MIT License. Introduction This is a pure numpy implementation of the coherent point driftCPDalgorithm by Myronenko and Song for use by the python community. It provides three registration methods for point clouds: 1) Scale and rigid...
have been proposed that affect all phases of the algorithmfromthe selection and matching of points to the minimization strategy [3]. Nonetheless ICP requires that the initial pose of the two point sets be adequately close, which is not always possible, especially when transformation is non-rigid...

as lines and planes, present substantial challenges for existing registration algorithms, such as Coherent Point Drift(CPD), Fast Global Registration(FGR), and Four Points Congruent Sets(4PCS). To address these challenges, we develop a novel algorithm, namely, for the registration of forest point...
The Coherent Point Drift for Clustered Point Sets The problem of non-rigid point set registration is a key problem for many computer vision tasks. In many cases the nature of the data or capabilities of the point detection algorithms can give us some prior information on point sets distribution...
In this paper we explore use of prior information about point sets clustering, such information can be obtained with preliminary segmentation. We extend existing probabilistic framework for fitting two level Gaussian mixture model and derive closed form solution for maximization step of the EM algorithm...
