چکیده

There have been some new advances in shape analysis (labelled and unlabelled) and directional statistics. The real push has come from applications in bioinformatics and images. We consider a few topics mostly coming from my collaborative work! The topics considered are as follows: • 3D reconstruction from 2D views (labelled) • Bayesian hierarchical alignment (unlabelled shape) • Directional models (unlabelled shape) Some other shape topics in pattern recognition have been covered in Mardia (2007).

Directional Statistics and Shape

There have been various developments in shape analysis in the last decade. We describe here some relationships of shape analysis with directional statistics. For shape, rotations are to be integrated out or to be optimized over whilst they are the basis for directional statistics. However, various concepts are connected. In particular, certain distributions of directional statistics have emerge...

A Comparative Study of Some Clustering Algorithms on Shape Data

Recently, some statistical studies have been done using the shape data. One of these studies is clustering shape data, which is the main topic of this paper. We are going to study some clustering algorithms on shape data and then introduce the best algorithm based on accuracy, speed, and scalability criteria. In addition, we propose a method for representing the shape data that facilitates and ...

The directional hybrid measure of efficiency in data envelopment analysis

The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

Directional Antenna-based Medium Access Control and Routing for AD HOC Networks: Challenges and Solutions

An area of growing interest has been to apply directional antennas to MANET protocols, which typically assumed a uniform equipment of omnidirectional antennas. In contrast to omnidirectional antennas, directional antennas have the benefits of reduced collision and extension of communication distance in a narrower range of directions. Existing work that applies directional antennas to MANET most...
