Fundus camera imaging of the retina is widely used to diagnose and manage ophthalmologic disorders including diabetic retinopathy, glaucoma, and age-related macular degeneration. Retinal images typically have a limited field of view, and multiple images can be joined together using an image registration technique to form a montage with a larger field of(More)

Without their help, I would never had the chance to get in touch with the state-of-the-art research, meet the leading scientists in the world and study here at the(More)
Fundus camera imaging of the retina is widely used to document ophthalmologic disorders including diabetic retinopathy, glaucoma, and age-related macular degeneration. The retinal images typically have a limited field of view due mainly to the curvedness of human retina, so multiple images are to be joined together using image registration technique to form(More)
We study the validity of the Jarque-Bera test for a class of univariate parametric stochastic differential equations (SDE) dXt = b(Xt, α)dt + dZt observed at discrete time points t n i = ihn, i = 1, 2,. .. , n, where Z is a nondegenerate Lévy process with finite moments, and nhn → ∞ and nh 2 n → 0 as n → ∞. Under appropriate conditions it is shown that(More)
