Kohonen Self Organizing for Automatic Identification of Cartographic Objects
Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...
متن کاملModified Physical Optics Approximation for RCS Calculation of Electrically Large Objects with Coated Dielectric
The Radar Cross Section of a target plays an important role in the detection of targets by radars. This paper presents a new method to predict the bistatic and monostatic RCS of coated electrically large objects. The bodies can be covered by lossy electric and/or magnetic Radar Absorbing Materials (RAMs). These materials can be approximated by the Fresnel reflection coefficients. The pro...
متن کاملEvaluation of sharpness measures and search algorithms for the auto focusing of high-magnification images
Digital imaging systems with extreme zoom capabilities are traditionally found in astronomy and wild life monitoring. More recently, the need for such capabilities has extended to long range surveillance and wide area monitoring such as forest fires, airport perimeters, harbors, and waterways. Auto-focusing is an indispensable function for imaging systems designed for such applications. This pa...
متن کاملAutomatic Reclustering of Objects in Very Large Databases for High Energy Physics
In the very large object database systems planned for some future particle physics experiments, typical physics analysis jobs will traverse millions of read-only objects, many more objects than fit in the database cache. Thus, a good clustering of objects on disk is highly critical to database performance. We present the implementation and performance measurements of a prototype reclustering me...
