WebJun 22, 2024 · The “optimally oriented flux” filter, first published in [ 10 ], evaluates a scalar measure of the flux flowing through a spherical surface. Before computing this value, directional information is extracted by projecting the gradient along “optimal” axes, and the flux measure then evaluated. WebEffective vessel enhancement and extraction steps by means of curvelet denoising and optimally oriented flux (OOF) filtering are first designed to produce 3D microvascular networks. Afterwards, a novel 3D data representation of OCT-A microvasculature is reconstructed via advanced mesh reconstruction techniques.

WebSep 7, 2024 · Also a curvilinear structure detector, called Optimally Oriented Flux (OOF) finds an optimal axis on which image gradients are projected in order to compute the image gradient flux . The second class of feature extraction techniques are in the form of unsupervised learning and transfer learning. These are mainly autoencoders and its … WebThe ESS is considered as an effective tool for enhancing the flexibility and controllability of a wind farm, and the optimal control scheme of a wind farm with distributed ESSs is vital to the stable operation of wind power generation. In this paper, a coordinated active and reactive power control strategy based on model predictive control (MPC) is proposed for … how to share scorm files

WebSep 10, 2024 · We first obtain a high-quality 3D representation of OCTA-based vessel networks via curvelet-based denoising and optimally oriented flux (OOF). Then, an effective 3D retinal vessel density mapping method is proposed. In this framework, a vessel density image (VDI) is constructed by diffusing the vessel mask derived from OOF-based analysis … WebApr 1, 2011 · The designed metric is well oriented along the direction of the vessel, admits higher velocity on the centerline, and provides a good estimate of the vessel radius. Based on the optimally oriented flux this measure is required to be robust against the disturbance introduced by noise or adjacent structures with intensity similar to the target ...
