应用多种数据融合方法对多时相SPOT图像处理提取三峡工程大坝区地面动态变化信息
Fusion of spot p and xs images by different methods in the landscape changes of dam area, yangtze three gorges project region, China
摘要
Abstract
In this paper, the problem of the influence of the acquisition dates for the improvement of the spatial resolution of images using data fusion is addressed. The studied area is the Three Gorges Dam on the Yangtze river in Sandouping area, China. Over the past several years, significant changes have taken place. The set of images to fused is composed of three SPOT panchromatic (P) images from 1990, 1997, 1998 and a multispectral SPOT XS image from 1998. Three algorithms are under concern: the High-Pass filtering (HPF) algorithm (Chavez et al. 1991), model RWM within the ARSIS concept (ARSIS-RWM) (Ranchin and Wald 1999) and the P+XS algorithm (Anonymous 1986). A comparison of the synthesised images demonstrates the possible misinterpretation that can result from an non-appropriated method. A quantitative assessment is then performed of the synthesised images. These two comparisons enhance the quality of the method derived from the ARSIS concept.关键词
