Comparing Different Classifiers for Automatic Age Estimation
(2004)
We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...
Process algebraic modelling and analysis of power-aware real-time systems
(2002)
A unified formal framework for designing and reasoning about power-constrained, real-time systems is described. The framework is based on process algebra, a formalism that has been developed to describe and analyse ...
Efficient cells-and-portals partitioning
(2006)
In this paper we revisit the cells-and-portals visibility methods, originally developed for the special case of architectural interiors. We define an effectiveness measure for a cells-and-portals partition, and introduce ...
Adaptive congestion protocol: A congestion control protocol with learning capability
(2007)
There is strong evidence that the current implementation of TCP will perform poorly in future high-speed networks. To address this problem many congestion control protocols have been proposed in literature which, however, ...
An integrated system for the segmentation of atherosclerotic carotid plaque
(2007)
In this paper, we propose and evaluate an integrated system for the segmentation of atherosclerotic plaque in ultrasound imaging of the carotid artery based on normalization, speckle reduction filtering, and four different ...
Effect of zooming on texture features of ultrasonic images
(2006)
Background: Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have ...
A new estimation scheme for the effective number of users in internet congestion control
(2011)
Many congestion control protocols have been recently proposed in order to alleviate the problems encountered by TCP in high-speed networks and wireless links. Protocols utilizing an architecture that is in the same spirit ...
Snakes based segmentation of the common carotid artery intima media
(2007)
Ultrasound measurements of the human carotid artery walls are conventionally obtained by manually tracing interfaces between tissue layers. In this study we present a snakes segmentation technique for detecting the ...
First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.
(2011)
Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...
On network survivability algorithms based on trellis graph transformations
(1999)
Due to the wide range of services being supported, telecommunications networks are loaded with massive quantities of information. This stimulates extra concern for network survivability. In this paper, we use graph theoretic ...
