1. A method to reduce scattering centers (SC) comprising: receiving a set of SC data points associated with an object in three-dimensional space; using a computer processor for: partitioning the SC data points into a plurality of volumes; aggregating the SC data points within each volume based on an aggregate threshold; combining the aggregated SC data points associated with each volume to form a reduced set of SC data points; comparing the reduced set of SC data points with the received set of SC data points to determine if the reduced set of SC data points meets a set of comparison metrics; and if the reduced set of SC data points meets the set of comparison metrics, increasing the size of the volumes and performing another iteration of reducing the SC data points by volume.
