Image Discrimination Models for Object Detection in Natural Backgrounds

Abstract

This paper reviews work accomplished and in progress at NASA Ames relating to visual target detection. The focus is on image discrimination models starting with Watson's pioneering development of a simple spatial model and progressing through this model's descendents and extensions. The application of image discrimination models to target detection will he described and results reviewed for Rohaly's vehicle target data and the Search 2 data. The paper concludes with a description of work we have done to model the process by which observers learn target templates and methods for elucidating those templates.
