Higher Order Statistics for Texture Analysis and Physical Interpretation of Polarimetric SAR Data

Texture Analysis of Polarimetric Sar

The Wavelet Polarization Signature (WASP) is a recently introduced formalism for analyzing the dependences of texture measures, in SAR imagery, afforded by wavelet frames on scale and polarization state. Based on a previously published theoretical approach, two experiments are reported where wavelet WASP analysis is applied to SAR observations of natural targets, both in the land and marine dom...

Evaluation of the Wishart Test Statistics for Polarimetric SAR Data

A test statistic for equality of two covariance matrices following the complex Wishart distribution has previously been used in new algorithms for change detection, edge detection and segmentation in polarimetric SAR images. Previously, the results for change detection and edge detection have been quantitatively evaluated. This paper deals with the evaluation of segmentation. A segmentation per...

asymptotic property of order statistics and sample quntile

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...

The Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection

The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
