Performance Modelling of Autonomous Electro-Optical Sensors (PM)
Abstract
The Performance Modeling of Autonomous Electro-Optical Sensors (PM) program is a basic research effort aimed at the fundamental analysis of image processing methodology. To this end, an investigation into the estimation and extraction of object boundary properties was initiated. During the prior six months, program activity has consisted of the definition and execution of an 'information compression' investigation. Throughout this study, the emphasis has been on analytic accuracy and not the speed of implementation. Briefly, the technical tasks performed during this effort were as follows: 1. Data collection. During this task, appropriate existing data was collected and cataloged. The resulting data base consisted of true targets (ie: Planes, Tanks, APCs, and Trucks) displayed through full ranges of rotation; 2. Boundary Extraction. Each image in the generated database was segmented so that the boundary of the associated target was easily accessible for additional study. 3. Data Compression. The boundaries produced during the prior task were data compressed. Specifically, each boundary was approximated by a piecewise linear contour. Several techniques were researched and implemented during this task: and 4. Testing. During this effort, the various compression methods were tested and compared based on accuracy, robustness and range of applicability.
