Optimally oriented flux

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.
