Abstract
This document describes a tool designed to assess the performance of detection algorithms when different atmospheric correction algorithms are employed to compensate for different, possibly detrimental, atmospheric and sensor hyperspectral image degradations. This is done by simulating atmospheric and sensor effects on background images, applying different correction algorithms to the generated images and running detection algorithms on the resulting images. Images with and without the presence of subpixel solid or gas targets are used to compute probability distributions of both detection and false alarms. These are then used to compute ROC curves that are useful for assessing each detection algorithm under the prevailing conditions. This tool was developed under contract W7701-125216/001/QCL on behalf of DRDC, Valcartier Research Center between September 6th 2012 and September 6th 2013.
