ملخص المقالة :
Up to now, several methods have been proposed for image fusion in pixel level and feature level for quality enhancement of satellite images. From these methods, methods based on discrete wavelet transform (DWT); intensity hue saturation (IHS); and high pass filtering have attracted much attention. But in methods based on; intensity hue saturation and discrete wavelet transform each have disadvantages such as chromatic aberration and linear discontinuity of location characteristics. The present article proposed a new and effective method for fusion in pixel and feature level and by combining the mentioned methods intelligently; the new proposed method maintains the significant and salient characteristics of input images and simultaneously overcomes the mentioned weaknesses. Results are product of experiments evidencing this claim
