An Efficient Image Fusion Technique Using Wavelet with PCA

摘要: Image fusion is a process in which high-resolution Panchromatic (PAN) combined with low resolution Multispectral (MS) to form new single image contains both the spatial information of PAN and spectral MS image. By applying wavelet transform alone, result often not good. Hence, when integrated any traditional method results are better. The decimated undecimated wavelets used can be categorized into three classes: Orthogonal, Biorthogonal, Nonorthogonal. In this study, technique proposed uses PCA for fusing IRS-1D images using LISS III scanner locations Vishakhapatnam Hyderabad, India. compared statistical performance measures analyzed. It was ascertained that superior other methods.
