Two-dimensional Fractional Brownian Motion in the analysis of medical images
Date of Original Version
This paper presents the preliminary results of the application of a two-dimensional Fractional Brownian Motion (FBM) model of image distribution. This model has proven successful in the interpretation of linear data as well as the segmentation of images. The approach taken by the authors difers from previous work in that rather than extractmg hnear data from the image and using a linear FBM model, the actual two-dimensional distribution is employed. It IS found that the resulting segmentation can be much more accurate than previous methods. However, due to the computational intensity of the problem, the algorithm as presently encoded results in a binary segmentation, rather than a 1:1 mapping from fractal dimension to grey level. Regardless of t tation produced, the sensitivity of the segmentation in the test cases exhibits great promise for this approach.
