OBJECTIVE The present study was aimed at evaluating the correlation between diffusion tensor imaging parameters and Loes score as well as whether those parameters could indicate early structural alterations. MATERIALS AND METHODS Diffusion tensor imaging measurements were obtained in 30 studies of 14 patients with X-linked adrenoleukodystrophy and were correlated with Loes scores. A control g...
A low level image processing, for examples, image denoising and finding a local structure in an image, is one of essential processes in computer vision. The nonlinear structure tensor [1] based on an anisotropic nonlinear diffusion processes has shown its capability for presenting useful information of an image, such as homogeneous regions, edges, and corners. The diffusion process to obtain a ...
We show how to reconstruct a two-dimensional surface, the drift field, and the diffusion tensor from a planar projection of trajectories of a diffusion process on the surface. The reconstruction is based on the stochastic differential equations of the projected motion, whose drift and diffusion tensor depend on the local curvature of the surface. The reconstruction process requires the solution...
