This Research contribution is about the Image Fusion, Pan-sharpening, Wavelets and filtering with Quality assessment, Satellite images are made by mapping high spatial resolution Pan chromatic images and high spectrally diverse Multi spectral images, the resulting pan sharpened image is misaligned. Our Research focuses on implementing satellite image fusion techniques for pan sharpening, correcting this misalignment and observing the effects of misalignment correction on the implemented methods through various quality assessment algorithms like SAM, UIQI and ERGAS. This book is suitable for BS & MS/Phd Research Scholars.
