Detailed Description

CorrespondenceRejectoVarTrimmed implements a simple correspondence rejection method by considering as inliers a certain percentage of correspondences with the least distances.

The percentage of inliers is computed internally as mentioned in the paper 'Outlier Robust ICP for minimizing Fractional RMSD, J. M. Philips et al'

Note: If setInputCloud and setInputTarget are given, then the distances between correspondences will be estimated using the given XYZ data, and not read from the set of input correspondences.

Author: Aravindhan K Krishnan. This code is ported from libpointmatcher (https://github.com/ethz-asl/libpointmatcher)
