Methods and systems for spatial filtering using a stochastic sparse tree grid

摘要

A computer-based method for processing data is described. The method includes receiving, at a processing device, data to be processed, processing the data to assign spatial information to the data, the spatial information defining an element on a grid, determining, with the processing device, a sparseness of the processed data through application of the processed data to a multiple resolution level sparse tree filter, placing the processed data within a histogram based on the determined sparseness, and filtering the data based on spatial statistics using a sparse histogram method.

1. A computer-based method for processing data, said method comprising:
receiving, at a processing device, data to be processed; processing the data to assign spatial information to the data, the spatial information defining an element on a grid; determining, with the processing device, a sparseness of the processed data through application of the processed data to a multiple resolution level sparse tree filter, wherein the multiple resolution level sparse tree filter includes multiple resolution levels with different grids within each level; placing the processed data within a histogram based on the determined sparseness; and filtering the data based on spatial statistics using a sparse histogram method.
