A Fourier Approach to 3D Local Feature Estimation from Volume Data

A Bhalerao and R Wilson

This paper describes an estimation and representation method for object structure in 3D image data. A windowed Fourier transform is used to estimate the parameters of 3D local structures (lines, planes and spheres) across a number of window sizes or scales. We present the estimation method and describe a decision process which aims to find the simplest object description. Preliminary results of the method on test data and blood vessels from magnetic resonance imaging are presented.
