The main aim of this paper is an improvement of the famous Scale Invariant Feature Transform (SIFT) algorithm used in place categorization. Masking approach to reduce the computational complexity of SIFT have been proposed. Tradeoff between key points and processing time on feature extraction has been used. Selected parameters used in the experiment demonstrated that the computational cost of SIFT...
Robotic systems, such as prosthetics and exoskeletons, offer people suffering from motor impairments a chance to regain lost physical functionality. However, the neural control that individuals are able to exert over these robots is currently limited. This is due to both lack of control authority in many degrees of freedom and insufficient sensory feedback through the human-robot interface. We propose...
Food planning and its quality evaluation is emerging as a very important aspect of modern civilization. With scientific vision and developments in agriculture, we can proficiently assess crop quality using various learning techniques which definitely substitute inconsistent, erratic and time consuming manual work. The use of fuzzy logic for crop quality has successfully proves its worth and establishes...
This paper describes the design of a professional development workshop on integrating robotics at the elementary and secondary school curriculum. The workshop was designed to support STEM education through teacher education at the university and post-university level. Moreover, the workshop leveraged the Technology Acceptance Model (TAM) and an interdisciplinary approach to engage teachers with robotics...
“SUZA — from school to science and the academic community” is the official popularization program for science, technology, engineering and mathematics at University of Zagreb, Faculty of electrical engineering and computing. Volunteers in the program are professors, researchers and students from the Faculty. Although, the program is relatively new, it counts more than 20 activities during a school...
One of the major problems faced by consumers while shopping at a supermarket is the inability to locate items and also to carry goods to the billing counter. In this paper, we describe a novel cost-effective method to overcome these issues by creating a smart trolley using a web camera along with video processing to complete the tasks. In comparison with previous methods which utilize RFID transceivers,...
In recent times, biomedical technology has received a major boost due to advancements in electronics. Sophisticated surgical instruments and patient monitoring devices have not only eased the burden on the doctors shoulders but have also taken patient care to a whole new level. However, the field of dentistry is yet to experience a major surge of technological innovation particularly when it comes...
The Smart Grid, with its explosion of distributed intellect, field mechanization, remote sensors and its deluge of new endpoint data, is driving the efficient combination of new distribution management capabilities into existing Energy Management Centres. Business benefits include greater efficiencies, more productive operations, improved service reliability, better asset management and more insightful...
In this paper, we overview basic quantum machine learning algorithms and we highlight their potential application for rehabilitation brain computer interface systems. The paper provides a very brief introduction to basic quantum theory issues, such as quantum registers and quantum gates, as well as basic limitations of brain computer interface systems. Finally, we present references, ideas and research...
Based on the recent research and statistics by Symantec, significant amount of all global web traffic and email traffic is marked as spam. Spambot is basically a robot that maliciously traverses the World Wide Web (WWW), and gathers information, email addresses, etc. For the spammer. The increasing growth of spam bot sophistication advances in the introduction of Spam 2.0, which infiltrate legitimate...
An electric wheelchair is basically acknowledged for mobility improvement in disability patients. In some cases, their hand could not well function. They may tire easy before reaching to the desired destination. Furthermore, the safety is the most concerned issue for wheelchair control in disability patients. Therefore, this work tries to develop the prototype of the automated navigation system that...
The aim of this paper is to support the idea that not only the robots behaviours, but also development/experience of the participant matters, when teaching a robot. The results presented encourage us to look more closer in the interplay between teacher and learners perspective to create the robots behaviour for a natural interaction. The results, therefore, provide both insights into individual differences...
Computing in schools has gained momentum in the last two years resulting in GCSEs in Computing and teachers looking to up skill from Digital Literacy (ICT). For many students the subject of computer science concerns software code but writing code can be challenging, due to specific requirements on syntax and spelling with new ways of thinking required. Not only do many undergraduate students lack...
Our current students belong to a new generation that lives with Internet, uses computers, and plays video games as natural skills. For that generation, education based on traditional classes is difficult. In this contribution, we propose learning RADAR fundamentals by using video games. The newly designed game is described, and has been tested by a group of students. Their learning results are promising...
Aim of this paper is to present a radio communication system that can be easily integrated in an emergency communication network, which is able to relay analog and digital data. Implementation of a multiprocessor radio network controller, based on the FPGA technology, is the main goal of this project. This configuration allows a multiple possibilities of communication: APRS data transmission and analogue...
The instruments BCI (brain-computer interface), are currently breaking into the vast horizon of bioengineering, favoring people with brain deficiencies, which sometimes is the only way to communicate. The main objective is to acquire brain signals to achieve an interface capable of receiving a response from the computer; and control a robotic arm. This paper provides a description of brain signals:...
Behavior Trees (BTs) have become a popular framework for designing controllers of in-game opponents in the computer gaming industry. In this paper, we formalize and analyze the reasons behind the success of the BTs using standard tools of robot control theory, focusing on how properties such as robustness and safety are addressed in a modular way. In particular, we show how these key properties can...
We present the first decentralized multi-copter flock that performs stable autonomous outdoor flight with up to 10 flying agents. By decentralized and autonomous we mean that all members navigate themselves based on the dynamic information received from other robots in the vicinity. We do not use central data processing or control; instead, all the necessary computations are carried out by miniature...
Physical symbol systems, for general intelligent action, take a physical stimulus as one object in the human world, whereas biological intelligent systems may take it as fundamentally different objects. For eliminating this conflict, the relative perception system hypothesis is proposed as a novel position for the nature of intelligence, based on the principle of world's relativity. From the hypothesis,...
Blind or visually impaired people want to know more about things they hear in the world. They want to know what other people can “see”. With its cameras, a robot can fill that role. But how can an individual make requests about arbitrary objects they can only hear? How can people make requests about objects they do not know either the exact location of, or any uniquely identifiable traits? This work...
