Nonuniform Image Reconstruction Using Multilevel Surface Interpolation
نویسنده
چکیده
This paper describes a fast algorithm for nonuniform image reconstruction. A multiresolution approach is formulated to compute a C2-continuous surface through a set of irregularly spaced samples. The algorithm makes use of a coarse-to-fine hierarchy of control lattices to generate a sequence of surfaces whose sum approaches the desired interpolating surface. Experimental results demonstrate that high fidelity reconstruction is possible from a selected set of sparse and irregular samples.

Iterative Tomographic Image Reconstruction Using Nonuniform Fast Fourier Transforms
Fourier-based reprojection methods have the potential to reduce the computation time in iterative tomographic image reconstruction. Interpolation errors are a limitation of Fourier-based reprojection methods. We apply a min-max interpolation method for the nonuniform fast Fourier transform (NUFFT) to minimize the interpolation errors. Numerical results show that the min-max NUFFT approach provi...
متن کاملImage Reconstruction for Arbitrarily Spaced Data Using Curvature Interpolation
The article is concerned with image reconstruction for arbitrarily spaced data using curvature interpolation. Image reconstruction is a challenging problem when no constraint is imposed on data locations. The problem is illposed and most numerical methods become overly expensive as the number of sample points increases. This article develops an effective partial differential equation (PDE)based...
متن کاملSurface reconstruction of detect contours for medical image registration purpose
Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...

متن کاملAn O(n 2 Log N) Multilevel Backprojection Method
A number of imaging technologies reconstruct an image function from its Radon projection using the convolution backprojection method. The convolution is an O(N 2 log N) algorithm, where the image consists of N N pixels, while the backpro-jection is an O(N 3) algorithm, thus constituting the major computational burden of the convolution backprojection method. An O(N 2 logN) multilevel backprojec...
