3-D texture characterized by accessibility measurements, based on the grey weighted distance transform

the role of task-based techniques on the acquisition of english language structures by the intermediate efl students

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

A Method for Defuzzication by Weighted Distance

Weighted Convolution Measure Algebras Characterized by Convolution Algebras

The weighted semigroup algebra Mb (S, w) is studied via its identification with Mb (S) together with a weighted algebra product *w so that (Mb (S, w), *) is isometrically isomorphic to (Mb (S), *w). This identification enables us to study the relation between regularity and amenability of Mb (S, w) and Mb (S), and improve some old results from discrete to general case.

Distance-based accessibility indices

The paper attempts to develop a suitable accessibility index for networks where each link has a value such that a smaller number is preferred like distance, cost, or travel time. A measure called distance sum is characterized by three independent properties: anonymity, an appropriately chosen independence axiom, and dominance preservation, which requires that a node not far to any other is at l...

Real-Time Texture-Based 3-D Tracking

We present a tracking approach for textured surfaces which recovers the object motion in 6 degrees of freedom. We assume an arbitrary but known surface shape, and an image of the object at a known reference pose. We extend the 2-D tracking framework of Hager et al. [1] to tracking in 3-D and under full perspective projection. The algorithm is evaluated to ground-truth motion and shows high accu...
