Abstract
A method comprises loading LADAR point data into a three-dimensional voxel array as a plurality of components (304); determining connected components in the array (306); determining a size for each component and a hit count of occupied voxels (316); and determining whether each occupied voxel is to be written to an output file (312), wherein occupied voxels are written (312) to the output file according to a set of criteria based on statistics for determining when a voxel represents a light pulse reflected by a physical object.
