Statistical Analysis of Northern Australian Land Backgrounds

摘要

A substantial amount of work into the statistical analysis of both visual and infra-red imagery has been undertaken in the recent years at DSTO. This report is a summary of the results from the analysis of a trial held in Northern Australia in 1997. The first and second order statistics of land background infra-red pixel intensities were estimated and Gaussian histogram and power-law auto-covariance models were rigorously tested, before a stochastic simulation of the data was performed. As the simulation technique required Gaussian statistics, a point-wise non-linear transform was applied to those ensemble images with non-Gaussian histograms.
