2015/12/9
An efficient statistical algorithm of automatic extracting road from SAR images is devised in this paper. First, an feature detecting operator is used to find the road candidate. Then another smaller ...
Multipolarimetric SAR image change detection based on multiscale feature-level fusion
Multipolarimetric SAR Change Detection NSCT Fusion
2015/7/27
Many methodologies of change detection have been discussed in the literature, but most of them are tested on only optical images or traditional synthetic-aperture radar (SAR) images. Few studies have ...
PRECISE ORIENTATION OF SPOT PANCHROMATIC IMAGES WITH TIE POINTS TO A SAR IMAGE
Image orientation stereoscopic multisensor SAR SPOT parallax
2015/3/24
The extraction of spatial data from satellite imagery requires that precise sensor models are used to orientate images. This is
particularly important with images acquired by linear sensors, such as...
SAR复图像配准是干涉SAR数据处理中的关键步骤之一，配准精度直接影响后续产品的质量。本文提出了一种基于联合实、复相关函数的星载干涉SAR图像配准方法。首先，在分析已有配准测度函数各自特性的基础上，结合国际上干涉SAR数据处理经验，得出了在全球干涉测量任务背景下，稳健、普适性的干涉SAR图像配准方法应该以相关函数作为其配准测度函数这一结论。然后，针对相关函数存在实、复相关计算两种，分析了实、复相关...
