What does multisensor image fusion add in terms of information content for visual interpretation

摘要: Image fusion or the merging of images recorded at different spatial resolutions is widely applied in various fields remote sensing. Often aim to increase visual content an image as result low-spatial resolution-high spectral resolution imagery with a high image. The effect that may be expected from such cosmetic improvements was quantified by calculating statistics and variograms original, 30 m Landsat Thematic Mapper (TM) spatially degraded products 90m 150 resolution. analysis shows increasing does not affect mean median histograms, however standard deviation decreases spread histogram decreases. rate change dependent on structure which reflected variogram. For homogeneous data (e.g. little continuity short value ...
