Saving energy in Wireless Sensor Networks is essential to extend the lifetime of in-field deployments. Previous research has shown that communication is generally the most energy consuming task and needs to be reduced in order to build resource-efficient long-term applications. The communication demand for retrieving query results from deep within the sensor network is typically high. As a result,...
Logos sometimes also known as trademark have high importance in today's marketing world. Products, companies and different gaming leagues are often recognized by their respective logos. In this paper, an implementation system for logo detection and recognition in video stream is presented. Feature set using SIFT (Scale Invariant Feature Transform) key-points is created for each query logo and the...
In text categorization, one well-known document representation is bag-of-words. Although it is simple and popular, it ignores semantics, underlying linguistic information, and word correlations. In this paper, a new representation for text data is proposed which is called Bag-Of-Queries (BOQ). First, a taxonomy of the terms in the local vocabulary is extracted. Extracting a taxonomy is performed by...
In monitoring a patient's real-time vital signs through Body Area Networks (BAN), rich data sources are communicated to medical practitioners. It is essential that data is delivered in timely-context aware manner. In this paper a system is designed for patients with cardiac disorders, with an emphasis on the design of the sensing device and communication scheme chosen. Several existing wearable physiological...
Interactive user interfaces are important in user friendly software development. This paper proposes an approach of introducing a specific user interface. This interface is specifically developed a diagnosis screen to enter efficiently patient's diagnosis details. We discuss various aspects and techniques for providing efficient way to enter diagnosis details in a very effective manner. However, there...
This paper presents an optimization methodology of hybrid multi-objective genetic algorithm for the real world optimization problem of facial analysis of multiple camera images by 2.5D Active Appearance Model (AAM). Facial large lateral movements make acquisition and analysis of facial images by single camera inefficient. Moreover non-convex multidimensional facial search space formed by AAM requires...
In this paper, we present ACPSO a new dynamic image clustering algorithm based on particle swarm optimization. ACPSO can partition image into compact and well separated clusters without any knowledge on the real number of clusters. It uses a swarm of particles with variable number of length, which evolve dynamically using mutation operators. Experimental results on real images demonstrate that the...
Tens of thousands of universities are today educating students with different methods for a vast variety of majors. This paper aims to introduce Knowledge Tree (KT) as an integrated virtual structure to be used in the educational systems. A collaborative structure is utilized to define a universal curriculum for various university majors worldwide to maximize e-learning capabilities. Then, a collaborative...
User initiated interactions in social networks and web services generate Collective Intelligence that is exploited in many web applications to shape output toward a better adaptation of users' information needs. Most of data involved in these interactions consists of multimedia information that needs to be identified, described and managed efficiently in order to be retrieved and shared on the web...
