Medical Image Registration Using the Fourier Transform
A Fourier Transform (FT) based pattern-matching algorithm was adapted for use in medical image registration. This algorithm obtained the FT of two images, determined the normalized cross-power spectrum of the transformed images, and then applied an inverse FT. The result was a delta function with a maximum value at the location corresponding to the distance between the two images; a similar met...
متن کاملMedical Image Registration Using B-Spline Transform
Hierarchical B-spline has been widely used for shape modeling in many fields. Registration result is achieved by minimizing a cost function which represents the cost associated with the image similarity. In this paper we present an application of this concept in the form of free-form deformation with a newly proposed metric. This new metric combines the mean square metric and the distance of bo...
متن کاملMedical Image Registration with Fourier basis Functions
Registration is one of the most interesting, yet challenging computer-aided tasks in medical image processing, aimed at bringing two or more data sets into spatial and/or temporal correlation. If the represented data are medical images, there are countless situations where it is of interest to attain such correlation, as it has become routine practice in many diagnostic and image-guided therape...
متن کاملImage registration for Fizeau Fourier transform imaging spectroscopy
Fourier transform imaging spectroscopy (FTIS) can be performed with a Fizeau imaging interferometer by recording a series of images with various optical path differences (OPDs) between subapertures of the optical system and postprocessing. The quality of the spectral data is affected by misregistration of the raw image measurements. A Fizeau FTIS system possesses unique degrees of freedom that ...
متن کاملImage Registration with Hyperspectral Data Based on Fourier-Mellin Transform
Hyperspectral imagery is playing more and more important role in many fields such as geology, agriculture, environment, military, atmosphere and so on. We need to register Hyperspectral imagery so that we can build coherent 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 related techniques fo...
