A Data-Driven Framework for Visual Crowd Analysis
(2014)
We present a novel approach for analyzing the quality of multi-agent crowd simulation algorithms. Our approach is data-driven, taking as input a set of user-defined metrics and reference training data, either synthetic or ...
Crowdsourcing emergency data in non-operational cellular networks
(2017)
In overloaded or partially broken (i.e., non-operational) cellular networks, it is imperative to enable communication within the crowd to allow the management of emergency and crisis situations. To this end, a variety of ...
High efficiency video coding for ultrasound video communication in m-health systems.
(2012)
Emerging high efficiency video compression methods and wider availability of wireless network infrastructure will significantly advance existing m-health applications. For medical video communications, the emerging video ...
Atherosclerotic plaque ultrasound video encoding, wireless transmission, and quality assessment using H.264
(2011)
We propose a unifying framework for efficient encoding, transmission, and quality assessment of atherosclerotic plaque ultrasound video. The approach is based on a spatially varying encoding scheme, where video-slice ...
Segmentation of the common carotid intima-media complex in ultrasound images using active contours
(2012)
The segmentation of the intima-media complex (IMC) of the common carotid artery (CCA) wall is important for the evaluation of the intima media thickness (IMT) on B-mode ultrasound (US) images. The IMT is considered an ...
A fully automated method using active contours for the evaluation of the intima-media thickness in carotid US images.
(2011)
The thickness of the intima-media complex (IMC) of the common carotid artery (CCA) wall is important in the evaluation of the risk for the development of atherosclerosis. This paper presents a fully automated algorithm for ...
A hybrid fault-tolerant algorithm for MPLS networks
(2008)
In this paper we present a new fault tolerant, path maintaining, algorithm for use in MPLS based networks. The novelty of the algorithm lies upon the fact that it is the first to employ both path restoration mechanisms ...
Clustering attributed multi-graphs with information ranking
(2015)
Attributed multi-graphs are data structures to model realworld networks of objects which have rich properties/attributes and they are connected by multiple types of edges. Clustering attributed multigraphs has several ...
Exploitation of medical crisp database for fuzzy diagnostic decision support systems
(2015)
There are several types of Diagnostic Decision Support Systems (DDSS) but all move towards a common direction: provide assistance to the doctors/clinicians to make the right diagnosis for a specific patient, minimizing as ...
Performance vs. freshness in web database applications
(2014)
In this work, we present a novel approach for the efficient materialization of dynamic web pages in e-commerce applications such as an online retail store with millions of items, hundreds of HTTP requests per second and ...
