Redefining automatic target recognition (ATR) performance standards

Proceedings of SPIE, 2011
Present descriptors for Automatic Target Recognition (ATR) performance are inadequate for use in comparing algorithms that are purported to be a solution to the problem. The use of receiver operator characteristic curves (ROCs) is a defacto standard, but they do not communicate several key performance measures, including (i) intrinsic separation ...

A fuzzy hyperspectral classifier for automatic target recognition (ATR) systems

Pattern Recognition Letters, 1999
In this paper we present a fuzzy system based hyperspectral classifier for automatic target identification. The system is based on partitioning the spectral band space into clusters using a modified fuzzy C-Means clustering algorithm. Classification of each pixel is then carried out by calculating its fuzzy membership in each cluster.

Improved automatic target recognition (ATR) value through enhancements and accommodations

SPIE Proceedings, 2006
There is a strong and growing need for automatic target recognition (ATR) technologies. Those technologies have made great strides; however, there is a general sense that they are not having the full impact desired. This paper develops a value-based framework for considering how ATR technology can be made more relevant and then introduces and ...

Geospatial feature based automatic target recognition (ATR) using data models

Proceedings of SPIE, 2010
We present a method for deriving an automatic target recognition (ATR) system using geospatial features and a Data Model populated decision architecture in the form of a self-organizing knowledge base. The goal is to derive an ATR that recognizes targets it has seen before while minimizing false alarms (zero false alarms). We present an investigation

General quantitative approach to performance evaluation of automatic target recognition (ATR) systems

SPIE Proceedings, 2001
This paper presents a general quantitative approach to performance evaluation of ATR systems, especially for FLIR imagery. The general quantitative evaluation approach we proposed consists of three main steps. First, multiple sets of testing image sequences with significantly varying difficulty for specific environment, which can be precisely measured,
