Background and Purpose-Initial clinical assessment or conventional diffusion tensor imaging parameters alone do not reliably predict poststroke recovery of motor function. Recently, local diffusion homogeneity (LDH) has been proposed to represent the local coherence of water molecule diffusion and can ...

Mapping local functional homogeneity in schizophrenia patients and healthy controls. Group mean 2dReHo maps are depicted for early-onset schizophrenia (EOS; a), adulthood-onset schizophrenia (AOS; b), typically developing controls (TDCs; c) and healthy adult controls (HACs; d). Maps of group ...
A fast segmentation approach for multi-band remote—sensing images was proposed.First,remote—sensing images were quantized.Second,local homogeneity gradient images were produced based on quantization results.Third,a fast watershed transform was applied to gradient images to perform initial segmentation.Fina...
Diffusion of protons around the local magnetic field induced by MNPs may lead to the loss of proton spin coherence, namely dephasing, which forms the fundamental basis ofT2contrast agents36,37. Although manufacturers have taken great efforts to make a uniform magnet, the magnetic field in an MRI...
the magnitude of the temperature gradient is changed, confirming that the system is controlled solely by the solutal Rayleigh number, and that the slowing-down is dominated by a combined effect of the driving force of buoyancy, the dissipating force of diffusion and the confinement provided by the...
An Adaptive Non-local Means Filter Based on Region Homogeneity In this paper, a local scale measure is presented for the detection of homogeneous regions in an image. Then, based on region homogeneity, an adaptive nonl... L Xia,H Shen,L Zhang - Seventh International Conference on Image & ...
This has motivated the recent diffusion of works in the literature, focusing on the mechanical behavior of FG and/or homogenous nano-sized beams. A nonlocal elasticity theory, for example, was suggested by Peddieson et al. [90] to study the nonlocal behavior of Benoulli/Euler beams. In ...
We used standard parameters for the diffusion map embedding, as it is a widely used technique5,15,18,57,58. However, the algorithm has a number of parameters to set: the density of the FC matrix (default: 10% density); the anisotropic diffusion parameter α, which controls the influence ...
Correlation describes the local homogeneity of the input image (the original SUV image or its decompositions). The more similar in intensity a voxel was to its neighbors, the larger the correlation would be. The correlation would be close to 1 if the intensities of the voxels within a VOI ...
