TL;DR: Two principles for digitalrelation are presented, one based on referring photographic densities to object points in an object coordination system and the other based on searching the sterEO model in EPIPOLAR PLANES and can be used in mapping applications.
Abstract: TWO PRINCIPLES FOR DIGITAL CORRELATION ARE: ONE IS BASED ON REFERRING PHOTOGRAPHIC DENSITIES TO OBJECT POINTS IN AN OBJECT COORDINATE SYSTEM AND CAN BE USED IN CHANGE DETECTION IN THE OBJECT; THE OTHER IS BASED ON SCANNING THE STEREO MODEL IN EPIPOLAR PLANES AND CAN BE USED IN MAPPING APPLICATIONS. THE PRINCIPLES SIMPLIFY THE PROBLEM OF CORRELATION. A PROTOTYPE INCORPORATES THE PRINCIPLES.

TL;DR: A general model is presented for calculating detection and falsealarm probabilities for the automated change detector and the model is then applied to determine PD'PF for the "target-no target" type change.
Abstract: A general model is presented for calculating detection and falsealarm probabilities for the automated change detector. The model is then applied to determine PD'PF for the ?target-no target? type change; the resulting PD and PF are compared to the one-channel case.
