# Aspects of the Detection of Scene Congruence

## Abstract

The problem of matching two scenes . one contained in the other. arises in many practical picture processing tasks including stereocompilation. classification of photographic data . and map matching for navigation and guidance . Because the images are not exact replicas . but rather noisy and perhaps geometrically distorted versions of the original scenes, it is necessary to develop a body of theory capable of providing answers to questions concerning effects of various types of error, and means for minimizing th-e effects of such errors . This paper presents a "decision space" approach to the problem for dealing with small amounts of noise and distortion, and a promising new technique for dealing with "rubber sheet" distortion.
