 Abstract—Hyperspectral imagery is playing more and moreimportant role in many fields such as geology, agriculture,environment, military, atmosphere and so on. We need toregister Hyperspectral imagery so that we can buildcoherent image cubes and get coherent spectrum of pixels.Our concern in this paper is the Fourier-Mellin Transform(FMT) for image registration process and its relatedtechniques for real hyperspectral data. FMT can recovertranslation, rotation. It is computationally efficient.Techniques such as filter, window and downscale forimproving precision in the registration process aretaken/put forward and discussed. With highpass emphasisfilter and downscale for registration of real hyperspectraldata can get a right or better result in some situation.

Index Terms—image registration, hyperspectral, Fourier-Mellin transform, log-polar transform, remote sensing
