在论文《Point-Set Registration: Coherent Point Drift》中介绍了刚性和非刚性的配准概率方法,称为一致性点漂移算法。论文将点集之间的对应关系看成是一种概率关系问题,在最理想情况下真正的对应点的概率是1,错误的对应点概率值是0,所以直接避开点之间的坐标关系而转向使用概率值来描述这种对应关系,如果概率值越大,...

In contrast, the farthest point, which we denote here to have depth \(\varDelta f+\varDelta {f}_{r}\) from the focal plane, would have the most number of CTF rings. The aberration parameter \(\widetilde{\chi }\left({k}_{{{\mathrm{lim}}},\varDelta f\right)\) (Eq. (17)) ...
In this post we'll show an experiment that we performed which was to pinpoint the location of a transmitter using KerberosSDR's coherent direction finding capabilities. RF direction finding is the art of using equipment to determine the location of a transmitting signal. The simplest way is ...
To cancel out the slow drift of the background signal, the charge sensor signal in (102) is recorded before every spin manipulation at point O and it is subtracted from the integrated signal at M1. The whole-pulse cycle is repeated for N = 200 times to infer the singlet-return ...
a prominent deviation is evident. This is caused by a shift of about one pixel, of the center of intensity along the lateral direction of the beam. The cause of this shift is a drift in pointing of the offset mirrors on the beam-defining aperture of the KB mirrors for the CXI beamline...
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...
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....
