Multispectral IKONOS Image Segmentation Based on Vector Field Model
Land Cover Segmentation Image Processing Automation Feature Extraction Quickbird
2015/12/17
Image segmentation is a valuable approach that performs an object-based rather than a pixel-based analysis of high-spatial resolution satellite image. A multiscale approach for segmenting the pan-shar...
Semi-Automatic Extraction of Different-Shaped Road Centerlines from Ms and Pan-Sharped IKONOS Images
Image processing Road extraction Space photogrammetry Clustering Updating
2015/12/9
In this work we develop semi-automatic road extraction system for updating and storage road network data bases. Combination of some of the existing road extraction techniques such as spectral and spat...

IKONOS-2卫星影像纠正及精度分析
IKONOS-2卫星影像纠正 一般多项式法 有理函数法
2009/8/10
随着遥感技术、计算机技术的发展,遥感已经从高端的科学研究步入实际应用的各个领域。特别是美国SpaceImage公司于1999年9月26日发射了世界上首颗高分辨率商业卫星IKONOS-2,这标志着高分辨率的遥感时代已经来临。其1米分辨率的卫星影像使对地观测达到了一个新阶段--既能满足“数字地球”的需要,也能代替航空摄影并满足工程勘察的需要。本文在研究遥感图像的一般多项式法、有理函数法等多种纠正方法...
