Knowledge-Based Interpretation of Satellite Data for Safeguards Purposes by Object-Based and Multi-Scale Image Analyis

چکیده
The use of commercial satellite images for the verification of nuclear treaties has been suggested recently in the context of a new protocol extending the rights of the International Atomic Energy Agency (IAEA) to verify the absence of undeclared nuclear activities within its member states. The present work investigates the application of a relatively new technology for image analysis (eCognition), namely a procedure for object-oriented and multi-scale image analysis in semantic networks. The aim of this study is to examine the possibilities of knowledge-based classification for change detection and object recognition in the context of nuclear safeguards.

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

متن کاملObject Level Strategy for Spectral Quality Assessment of High Resolution Pan-sharpen Images
Panchromatic and multi-spectral images produced by the remote sensing satellites are fused together to provide a multi-spectral image with a high spatial resolution at the same time. The spectral quality of the fused images is very important because the quality of a large number of remote sensing products depends on it. Due to the importance of the spectral quality of the fused images, its eval...
