Image fusion is finding its application in all spheres of life like medical, military, geological etc. The aim of Image fusion is to combine the information of same scene images taken from different sensors or the images with focus on different objects. Fused image is more informative and better in quality. In this paper, a hybrid technique is developed and carried out a detailed comparative analysis with the existing techniques based on RGB contents, Entropy of the image. This paper is based on considering the remote sensing application General TermsImage fusion, PCA, Wavelet Transforms, Hybrid Technique.
