Research Journal of Information Technology1815-74322151-7959Science International10.3923/rjit.2011.12.23Yuhendra SumantyoJoshapat Tri KuzeHiroaki 1201131Pan-sharpening is also known as image fusion, resolution merge, image integration and multi sensor data fusion has been widely applied to imaging sensors. The purposes of pan-sharpening is to fuse a low spatial resolution multispectral image with a higher resolution panchromatic image to produces an image with higher spectral and spatial resolution. In this paper, we are investigated these existing pan-sharpening methods based on visual and spectral analysis. And to achieve assess the accurate classification process, we proposed a Support Vector Machine (SVM) based on Radial Basis Function (RBF) kernel. In the Experimental results, a comparative performance analysis of techniques by various methods show that Gram-Schmidt followed by PCA perform best among all the techniques. Besides that, higher overall accuracy of Gram-Smidth (GS) fused image increase 0.90 percent. And also, the high producers and users accuracy average of Gram-Smidth (GS) fused for each of the classes and methods used was always reported greater than 91.8% and 91.11%, respectively, indicating the overall success of the performed classification. And producer accuracy he followed by PCA was 90.84% and user accuracy was 89.99.]]>Andrea, G. and N. Filippo,20074035683577Kumar, U., C. Mukhopadhyay and T.V. Ramachandra,20091173177Vijayaraj, V., N.
