In many applications, separable algorithms have demonstrated their efficiency to perform high performance and parallel volumetric computations, such as distance transformation or medial axis extraction. In the literature, several authors have discussed about conditions on the metric to be considered in a separable approach. In this article, we present generic separable algorithms to efficiently...

The study aims to investigate wind effects on the equal area and same height building model having plan cross-sectional shape in form of regular irregular bulidings. ratio modification is kept for shaped models because limited studies are available such type comparison. responses structure resist load increased by applying these modifications corner configuration as cut, chamfer, fillet structu...

We study the chamfer distance transformations of binary digital images and corresponding Lipschitz covers of grayscale images. Validity of the double scan algorithm in arbitrary dimension is proved.

In this paper, a model that takes into account the dependence of strength properties on damage rate is considered for modelling impact failure composite materials. The constants material are determined basis experimental diagrams to compression and shear loading unidirectional composite, which exhibit nonlinear strain rate. proposed implemented Abaqus finite element modeling software case three...

PURPOSE To investigate the effect of reducing tooth preparation and ceramic thickness on fracture resistance of lithium disilicate crowns. MATERIALS AND METHODS Specimen preparation included a standard complete crown preparation of a typodont mandibular left first molar with an occlusal reduction of 2 mm, proximal/axial wall reduction of 1.5 mm, and 1.0 mm deep chamfer (Group A). Another typo...

Liver Perfusion gives important information about blood supply of liver. However, in daily clinical diagnosis, radiologists have to manually mark the perfusion position in time-sequence images due to the motion of liver caused by respiration. In this paper, we propose a novel hybrid method using a variation of active contours and modified chamfer matching to automatically detect the liver perfu...

We present a vision system for the 3-D model-based t r acking of unconstrained human movement. Using image sequences acquired simultaneously f r om multiple views, we recover the 3-D body pose at each time instant without the use of markers. The pose-recovery problem is formulated a s a s e arch problem and entails nding the pose parameters of a graphical human model whose synthesized a p p ear...
