Point Cloud Filtering

Next up, we'll explore some of the most commonly used filters from the Point Cloud Library. These filters are:

VoxelGrid Downsampling Filter
ExtractIndices Filter
PassThrough Filter
RANSAC Plane Fitting
Outlier Removal Filter

While some of these are actual filters that use an underlying algorithm to improve the quality of your point cloud data, some are simple tools that are required at certain stages in your perception pipeline to aid in the extraction of a subset of the input point cloud.
