HYPERSPECTRAL AND MULTISPECTRAL IMAGE FUSION USING NSCT AND FDCT METHODS

Souvik Pal, Sonali Bhattacharyya, Srinath Doss, D.Akila, G.Suseendran.

Abstract
Image fusion plays an important role in computer vision, medical imaging, robotics, remote sensing and satellite imagery. Image fusion is a method or a process in which it produce all relevant information in a single image by combining two or more input images. The final image or final output contains more information than a single image. Hyperspectral image known as HIS and Multispectral image fusion known as MSI are used in wide array of application although it originally developed for geology and mining because of high spectral-resolution but it has low spatial-resolution. Non-Subsampled Contour let Transform known as NSCT. Hyperspectral and multispectral Image Fusion using NSCT and FDCT methods are used in this paper and it can be used in various fields like medical imaging, Satellite images, space research and remote sensing.

Key words: Hyperspectral image (HSI), Multispectral image (MSI), Non-Subsampled Contour let Transform(NSCT), Fast discrete curvelet transform(FDCT),
