F3l Filter

3D and 2D Filters.

Condition Removal

A Dimension-wise to filter with Upper-Bound and Lower-Bound Eg: x: -10 ~ 10, y: ~= 0, Z: 20 ~.

Pass Through

Target Dimension to filter with Upper-Bound and Lower-Bound

Radius Outlier Removal

Filter Numbers of point in radius.

Statistical Outlier Removal

Compute k-neighbors of all points, then compute mean and variance filter out mean +- multiply * std

Voxel Grid

Build a Dimension-wise grid, compute mean of points per grid.
