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-...
the coherent point drift (CPD) algorithm is rarely used because of two challenges: (1) volumetric deformation is difficult to predict, and (2) registration from intraoperative visible tissue surface to whole anatomical preoperative model is a "part-to-whole" registration that CPD cannot be applied...
一致性点漂移算法 (Coherent Point Drift, CPD)是一种鲁棒的基于高斯混合模型的点集匹配 算法。该算法适用于刚体以及非刚体变换下的多维 点集配准问题,对于噪声、出格点以及缺失点的影 响具有较强鲁棒性。但由于采用的是EM算法框架, 其存在两个缺陷: (1)对于迭代的初始点选取十分敏 ...
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 registration; 2) Affine registration; and 3) Gaussian regularized non-rigid registration....
Point Drift (CPD) method. Similar to [5], given two point sets, we fit a GMM to the first point set, whose Gaussian centroids are initialized fromthe points in the second set. However, unlike [4, 5, 9] which assumes a thin-plate spline transformation, we do not make any explic...
CPD配准算法及代码的简单理解(Coherent Point Drift) ,core文件夹中还有两个文件。cpd_make用于编译mex中的.c文件。由于计算两点间的距离需要用到多次的循环运算,为了代码效率,将计算距离部分以C语言实现,工具包使用了C语言和matlab语言混合...用途 首先简单介绍一下工具包中的各个文件作用。工具包下载下来后,里面一...
Multiple factors, including an unknown nonrigid spatial transformation, large dimensionality of point set, noise, and outliers, make the point set registration a challenging problem. We introduce a probabilistic method, called the Coherent Point Drift (CPD) algorithm, for both rigid and nonrigid point...
