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. WebOct 10, 2016 · use optimally oriented flux (OOF) (Law and Chung 2008) to detect curvilinear structures such as vessels. OOF relies on the measure of gradient flux through the boundary of local spheres. Compared to the Hessian-based filters, OOF is generally more robust against the disturbances induced by adjacent structures. i haven\u0027t decided where to go on holiday
