introduction: appropriate definition of the distance measure between diffusion tensors has a deep impact on diffusion tensor image (dti) segmentation results. the geodesic metric is the best distance measure since it yields high-quality segmentation results. however, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. the main goal of this ...

S. B. Al-Shaikh, S. Deshmukh,

Let $M$ be an orientable hypersurface in the Euclidean space $R^{2n}$ with induced metric $g$ and $TM$ be its tangent bundle. It is known that the tangent bundle $TM$ has induced metric $overline{g}$ as submanifold of the Euclidean space $R^{4n}$ which is not a natural metric in the sense that the submersion $pi :(TM,overline{g})rightarrow (M,g)$ is not the Riemannian submersion. In this paper...

We study the problem of representing all distances between $n$ points in ${\mathbb R}^d$, with arbitrarily small distortion, using as few bits possible. give asymptotically tight bounds for this problem, Euclidean metrics, $\ell_1$ (also known Manhattan)-metrics, and general metrics. Our metrics mark first improvement over compression schemes based on discretizing classical dimensionality reduc...
