Influence of Image Fusion Approaches on Classification Accuracy – A Case Study

摘要: While many studies in the field of image fusion remotely sensed data aim towards deriving new algorithms for visual enhancement, there is little research on influence other applications. One major application earth science land cover mapping. The concept sensors with multiple spatial resolutions provides a potential fusion. It minimises errors geometric alignment and atmospheric or temporal changes. This study focuses spectral classification their accuracy. A Landsat 7 ETM+ was used, where six multispectral bands (30 m) were fused corresponding 15 m panchromatic channel. methods comprise rather common techniques like Brovey, hue‐saturation‐value transform, principal component analysis, more complex approaches, including adaptive fusion, multisensor multiresolution technique, wavelet transformation. Image performed supervised met...
