Algorithms for Synthetic Aperture Radar Imagery VI.
Fundamental to the model-based paradigm of an Automatic Target Recognition (ATR) system is an accurate representation (a model) of the physical objects to be recognized. Detailed CAD models of targets of interest can be created using photographs, blu

In the present effort, we have built a new and improved model for the prediction of target acquisition. It is based on the latest models of early vision processes in the human visual system. It is a multi-channel model, based on three color opponent

This paper examines the applicability of computational vision models (CVM) to characterize thermal and visual imagery. A specific CVM model is described for the analysis of individual target characteristics and background clutter. A unique feature of

The current DoD target acquisition models have two primary deficiencies: they use simplistic representations of the vehicle and background signatures, and a highly simplified description of the human observer. The current signature representation oft

This paper investigates changes in target detectability due to alterations in target and clutter contrast structures brought about by sensor aliasing. A human observer model which is sensitive to structural contrast differences has been developed and
