The Barycentric Fixed-Mass method for estimating fractal dimensions
Updated Mon, 17 Aug 2015 18:02:25 +0000
Multifractal dimension estimation with the Barycentric Fixed Mass method. Covers a given 2D/3D point distribution with equal mass circles/spheres centered at each point and then applies two additional criteria:
1) Barycentric: A circle/sphere is considered only if its center point is the closest point to its barycenter.
2) Non-Overlapping: Barycentric circles/spheres are randomly chosen such that the overlap is minimized while maximizing the overall coverage
