Adjustable intensity-hue-saturation and Brovey transform fusion technique for IKONOS/QuickBird imagery
Optical Engineering: The Journal of SPIE
Among various image fusion methods, intensity-huesaturation ͑IHS͒ and Brovey transforms ͑BT͒ can quickly merge huge amounts of IKONOS/QuickBird imagery. However, spectral degradation often appears in the fused images. Moreover, IHS and BT suffer from individual color distortion on saturation compression and saturation stretching, respectively. To balance these two saturation changes during the fusion process, an adjustable IHS-BT approach with spectral adjustment is proposed.
