In this letter, a system combining compressive sensing (CS)-based image reconstruction and object detection algorithm is introduced. The use of CS is a promising approach for search-and-rescue applications, since it highly reduces the amount of data that needs to be transmitted. However, the high-quality reconstruction of such images is a challenging task due to the complexity of structures and the...

The discrimination of ECG signals is of crucial importance in clinical diagnoses of cardiac diseases. Manual analysis of ECG signals is very complex and time consuming task due to their composite nature. This paper proposes a novel scheme for reliable automatic classification of ECG signals into normal and three different abnormal (arrhythmia affected) categories. The feature extraction is based on...

This paper presents a novel gesture recognition system using a single three-axis accelerometer, that is to serve as an alternative or supplementary interaction modality for controlling mobile devices. Capturing, training and classification of the detected hand gestures are expected to be executed in their entirety on the mobile device running the proposed system, instead of being passed to a nearby...

Nowadays, many mobile devices are equipped with built-in inertial sensors. This spurred the research on new forms of communication between man and machines based on the movements or “gestures” performed by the user when holding the device. Here we discuss a gesture recognition system for controlling mobile devices with a wide range of possible practical applications. The system was designed to run...

Since gestures are a natural form of human expression, gesture-based interfaces can serve as an alternative interaction modality with numerous aspects to be utilized in human computer interaction. In this paper, we address the issue of finding a compact but effective set of features for a robust gesture recognition, using a single 3-axis accelerometer. A novel feature extraction scheme, that allows...

This paper introduces a new perspective for learning process and student-teacher relationship modeling. A possible framework for including pedagogy in such relationships, which can be applied to both face-to-face and online learning, is nowadays beginning to emerge. This framework combines individual possibilities and resources attributes, confronting them in a fair way. We found game theory - the...

The need to improve communication between humans and computers has been motivation for defining new communication models, and accordingly, new ways of interacting with machines. In many applications today, user interaction is moving away from traditional keyboards and mouses and is becoming much more physical, pervasive and intuitive. This paper examines hand gestures as an alternative or supplementary...
chapter
Understanding human gestures can be posed as a typical classification problem. Within the computer, gestures are represented as time-varying patterns in feature space. These patterns, though variable, are distinct and have associated meanings. In the absence of a priori knowledge of the underlying class probabilities, classification is performed based on some notion of similarity, e.g. distance, among...
chapter
Gestures, such as a wave or a nod, are commonly used in daily lives. While gestures are most often used just as a support for our verbal communication, they can also be used as a sole, simple and effective way of communication. Recent developments in sensor technology, that have reduced the costs of small and precise sensors and allowed them to be built in a growing number of everyday devices, have...

Information and communication technologies development has allowed new ideas in Internet based environments and services. Teaching and learning through the Internet enables to the client (student) to learn from anywhere and to the teacher to change and modernize lectures very easily. The new ideas about e-learning additional support are increasing, as learning through the Internet is getting more...
