Wide-Angle (WA) synthetic aperture radar (SAR) has shown remarkable performance in high-resolution mapping, and its mostly used imaging algorithm, fast factorized back projection (FFBP), is efficient, robust, of low computational complexity. However, trajectory deviations the system calibration error, introduced by measurement accuracy, dramatically degrade FFBP's performance. This article prop...

The primary objective of this work is to understand geometrical uncertainty based on the intrusive polynomial chaos method which allows computing the statistical output for geometrical uncertainty. Currently, very few techniques are available for such computations and this makes these computations a very active research topic. This article deals with the computation of some statistics of the so...

Point matching in multiple images is an open problem computer vision because of the numerous geometric transformations and photometric conditions that a pixel or point might exhibit set images. Over last two decades, different techniques have been proposed to address this problem. The most relevant are those explore analysis invariant features. Nonetheless, their main limitation all alone canno...

The process of developing architectural forms has greatly been changed by advances in digital technology, especially in design tools and applications. In recent years, the advent of graphical scripting languages in the design process has profoundly affected 3D modeling. Scripting languages help develop algorithms and geometrical grammar of shapes based on their constituent parameters. This stud...

SIMULGEO is a geometrical software developed for the position monitoring system of the CMS detector at the LHC accelerator. This software is capable to model opto-geometrical systems including error propagation and geometrical reconstruction. Thanks to a special description method, any opto-geometrical system can easily be described and analysed. This report explains how to use SIMULGEO, descri...
