A New Intensity-Hue with Color Distortion Reduction for IKONOS

Among the existing image fusion algorithms, Intensity used one. When the IHS method is used for IKONOS imagery, there is a significant color distortion, due mainly to the range of wavelengths in an IKONOS Pan ima regions are far larger than the grey values of intensity (I) and that vegetation appears of relatively high reflectance in Near Infrared (NIR) and Pan bands we propose a new technique Normalised Difference Vegetation Index (NDVI) to identify the vegetation area and then enhances it in the green (G) band by using the red (R) and the NIR bands. We obtain an intensity image with grey v grey values. Hence the color distortion in the fused image is reduced. Visual and statistical analyses prove that the concept of the proposed method is promising, and it significantly improves the fusion quality compared to co IHS techniques.
