Detailed Description
template<typename PointInT, typename PointOutT>
class pcl::MovingLeastSquares< PointInT, PointOutT >
MovingLeastSquares represent an implementation of the MLS (Moving Least Squares) algorithm for data smoothing and improved normal estimation.
It also contains methods for upsampling the resulting cloud based on the parametric fit. Reference paper: "Computing and Rendering Point Set Surfaces" by Marc Alexa, Johannes Behr, Daniel Cohen-Or, Shachar Fleishman, David Levin and Claudio T. Silva www.sci.utah.edu/~shachar/Publications/crpss.pdf
- Note
- There is a parallelized version of the processing step, using the OpenMP standard. Compared to the standard version, an overhead is incurred in terms of runtime and memory usage. The upsampling methods DISTINCT_CLOUD and VOXEL_GRID_DILATION are not parallelized completely, i.e. parts of the algorithm run on a single thread only.

Member Enumeration Documentation
UpsamplingMethod
| enum pcl::MovingLeastSquares::UpsamplingMethod |
| Enumerator | |
|---|---|
| NONE |
No upsampling will be done, only the input points will be projected to their own MLS surfaces. |
| DISTINCT_CLOUD |
Project the points of the distinct cloud to the MLS surface. |
| SAMPLE_LOCAL_PLANE |
The local plane of each input point will be sampled in a circular fashion using the upsampling_radius_ and the upsampling_step_ parameters. |
| RANDOM_UNIFORM_DENSITY |
The local plane of each input point will be sampled using an uniform random distribution such that the density of points is constant throughout the cloud - given by the desired_num_points_in_radius_ parameter. |
| VOXEL_GRID_DILATION |
The input cloud will be inserted into a voxel grid with voxels of size voxel_size_; this voxel grid will be dilated dilation_iteration_num_ times and the resulting points will be projected to the MLS surface of the closest point in the input cloud; the result is a point cloud with filled holes and a constant point density. |
