Nonlinear projection with curvilinear distances: Isomap versus curvilinear distance analysis
Dimension reduction techniques are widely used for the analysis and visualization of complex sets of data. This paper compares two recently published methods for nonlinear projection: Isomap and Curvilinear Distance Analysis (CDA). Contrarily to the traditional linear PCA, these methods work like multidimensional scaling, by reproducing in the projection space the pairwise distances measured in...
متن کاملUltrawide-field Fluorescein Angiography for Evaluation of Diabetic Retinopathy
PURPOSE To investigate the advantages of ultrawide-field fluorescein angiography (FA) over the standard fundus examination in the evaluation of diabetic retinopathy (DR). METHODS Ultrawide-field FAs were obtained in 118 eyes of 59 diabetic patients; 11 eyes with no DR, 71 eyes with nonproliferative diabetic retinopathy (NPDR), and 36 eyes with proliferative diabetic retinopathy (PDR), diagnos...
متن کاملUltrawide tuning of photonic microcavities via evanescent field perturbation.
Evanescent field perturbation of an integrated microring resonator is examined as a means of achieving high-fidelity reversible tuning of photonic microcavities over large wavelength ranges. A 1.7% wavelength tuning is achieved through the use of a novel silica fiber probe that provides access to the evanescent field of an air-clad high-index-contrast ring resonator. As the microring is perturb...
متن کاملUltrawide field imaging and sonography of a radial buckle.
Takkar B, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221761 Description A 78-year-old male presented with blurring of vision in right eye (RE) since 2 months. He was diagnosed to have retinal detachment in RE 27 years ago, which had been successfully repaired with scleral buckling surgery. Retinal holes had been treated with laser prophylaxis in left eye (LE). On examination, visual acuity ...
متن کاملFast Projection-Based Ray-Casting Algorithm for Rendering Curvilinear Volumes
ÐWe present an efficient and robust ray-casting algorithm for directly rendering a curvilinear volume of arbitrarily-shaped cells. By projecting cell-faces onto the image plane, we have effectively addressed three critical steps of the ray-casting process, namely finding the entry cell-faces for a ray, traversing along the ray from one cell to another, and reconstructing data values at the ray/...
