Fusion of multispectral and panchromatic images using improved IHS and PCA mergers based on wavelet decomposition
TL;DR: New fusion alternatives based on the same concept are presented, using the multiresolution wavelet decomposition to execute the detail extraction phase and the intensity-hue-saturation (IHS) and principal component analysis (PCA) procedures to inject the spatial detail of the panchromatic image into the multispectral one.
Journal ArticleDOI
Object- and pixel-based analysis for mapping crops and their agro-environmental associated measures using QuickBird imagery
Isabel Luisa Castillejo-González,Francisca López-Granados,Alfonso García-Ferrer,J. M. Peña-Barragán,Montserrat Jurado-Expósito,Manuel Sánchez de la Orden,María González-Audícana +6 more
TL;DR: A study of the accuracy of five supervised classification methods using multispectral and pan-sharpened QuickBird imagery to verify whether remote sensing offers the ability to efficiently identify crops and agro-environmental measures in a typical agricultural Mediterranean area characterized by dry conditions.
Journal ArticleDOI
A low computational-cost method to fuse IKONOS images using the spectral response function of its sensors
TL;DR: This paper presents a low computational-cost image fusion method based on the fast IHS transform, which uses the information of the spectral response functions of the low-resolution multispectral (LRM) and high-resolution panchromatic (HRP) sensors to minimize the spectral distortion problem.
Journal ArticleDOI
Multi-criteria evaluation of topographic correction methods
TL;DR: In this article, a multi-criteria analysis of widely used topographic correction methods is required that evaluates their performance over different sensors, terrain and temporal configurations, and different evaluation criteria have been used in the past, and there is not any simple and objective evaluation procedure to measure the quality of the correction.
Journal ArticleDOI
Influence of Surface Roughness Spatial Variability and Temporal Dynamics on the Retrieval of Soil Moisture from SAR Observations
Jesús Álvarez-Mozos,Niko E. C. Verhoest,Arantzazu Larrañaga,Javier Casalí,María González-Audícana +4 more
TL;DR: Results show that both field scale roughness spatial variability and its temporal variations are aspects that need to be taken into account, since they can introduce large errors on the retrieved soil moisture values.
