遥感影像融合与辐射校正顺序关系探讨
Study on order relation between image fusion and radiometric correction of remote sensing images
摘要
Abstract
With remote sensing images of Landsat-7 ETM+, SPOT-5, IKONOS and EO-1 ALI as test datum, the five models of radiometric correction and Pansharp algorithm have been used to study on the relationship between image fusion and radiometric correction. The ability of gaining high fre-quency information and the spectral fidelity were assessed by using visual and statistical analysis. The statistical methods include ERGAS, GVI and CC. The result shows that the high frequency information gained of the fusion images are the same regardless they are radiometrically corrected before or after fu-sion, and the spectral fidelity is related to the order between image fusion and radiometric correction.关键词
