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 …

WebSpeckle noise reduction is achieved via 3D curvelet denoising on OCT-A volumes. Afterwards, we exploit the optimally oriented flux (OOF) filter by considering its nice property of processing closely located curvilinear structures to enhance the dense OCT-A microvasculature as shown in Fig. 1(b). WebSo we place the shape term cliques at various positions and scales, choosing the can- didates using the Optimally Oriented Flux (OOF) [9]. The OOF computes the Hessian matrices at the boundaries of spherical regions.
