Thinning is a commonly used approach for computing skeleton descriptors. Traditional thinning algorithms often have a simple, iterative structure, yet producing skeletons that are overly sensitive to boundary perturbations. We present a novel thinning algorithm, operating on objects represented as cell complexes, that preserves the simplicity of typical thinning algorithms but generates skeleto...

We have compared the formation of oil drops in Newtonian and non-Newtonian fluids in a T-junction microfluidic device. As Newtonian fluids, we used aqueous solutions of glycerol, while as non-Newtonian fluids we prepared aqueous solutions of xanthan, a stiff rod-like polysaccharide, which exhibit strong shear-thinning effects. In the squeezing regime, the formation of oil droplets in glycerol s...

INTRODUCTION Neurodegeneration is an early component of diabetic retinopathy (DR). It is unclear whether neurodegeneration is an independent factor or a consequence of damaged retinal vasculature. The aims of this study were to review the literature concerning neurodegeneration in diabetic patients without or with early DR, and to examine whether neurodegeneration precedes visible vasculopathy ...

Thinning on binary images is an iterative layer by layer erosion until only the “skeletons” of the objects are left. This paper presents an efficient parallel 3D surface–thinning algorithm. A three–subiteration strategy is proposed: the thinning operation is changed from iteration to iteration with a period of three according to the three deletion directions.

Thinning is an iterative layer by layer erosion for extracting skeletons. This paper presents an efficient 3D parallel thinning algorithm which produces medial surfaces. A 3-subiteration strategy is proposed: the thinning operation is changed from iteration to iteration with a period of 3 according to the three deletion directions. 2002 Elsevier Science B.V.

MAIN OBJECTIVE The thinning of prelaminar tissue and prelamina cupping is known to occur by ischemia, as we see in anterior ischemic optic neuropathy. Since normal tension glaucoma (NTG) is thought to be more related to vascular factor than in primary open-angle glaucoma (POAG), we hypothesized that prelamina thinning may occur prominently in NTG patients. This study investigated the difference...

3D thinning algorithms are generally faster than any other connectivity-preservation skeletonization methods. However, most 3D thinning algorithms cannot guarantee to generate unit-width skeleton. This document describes an algorithm to generate unit-width skeleton based on 3D thinning and shortest path finding.
