The Iterative Closest Point(ICP)algorithm proposed by Besl and McKay[1]is a standard solution to the alignment problem.This iterative algorithm has three basic steps: 1.pair each point of P to the closest point in M;2.compute the motion that minimises the mean square error(MSE)be-tween the...

problem than what we need to have a correct recursive algorithm. We do not actually need a subroutine that, for every point sets, always correctly computes the closest split pair of points. Remember, there's a lucky case and there's an ...
do something only a little bit weaker. We need a linear time algorithm, which whenever the closest pair in the whole point set is in fact split, then computes that split pair in linear time. So let me now remind you of how that subroutine works. ...

Given a set of points and a radius $R$, the problem is, for every input point $p$, to identify all the other input points that are within a distance of $R$ from $p$. A naive deterministic algorithm can solve these problems in quadratic time. CPP as well as FRNNP play a vital ...
