In this paper the method for extraction of selected human body features, particularly dimensional units, is presented. The key parameters we focus on are the total human body height, arm length, leg length, shoulders distance and head height. Prototype software solution utilizes Histogram of Oriented Gradients (HOG) and Haar classifiers algorithms. The analysis of existing object detection approaches...
The aim of this paper is the proposal of the solution that is to enable identification of students based on their height and facial dimensions of specific face elements. Analysis of approaches that allow estimation of the height from the image is presented. Following the analysis, the experimental software solution is developed and consisted of two applications. The first enables the estimation of...
In this paper the elimination of image distortion and subsequent estimation of intrinsic camera parameters, while extracting the real object dimensions from photographs is presented. Research analysis includes description of the basic concepts related to the camera calibration. Following the analysis, the most suitable calibration method has been chosen and implemented as a software solution. The...
Artificial neural networks (ANN) are one of the dominant learning techniques used in the field of artificial intelligence and have significant assets as their properties imitate the behavior of neurons in human brain. In this paper is presented the research focused on ANN, specifically Multilayer perceptron (MPL) with the aim of detection of human face in the still image. This system was implemented...
The aim of this paper the extraction of human body dimensions using the latest Microsoft Kinect device. Another focus is the analysis of various application of this device in specific branches of science and research and its application in estimation of dimensions. Brief analysis of the device itself is carried out as well. The principal output of this paper the software application that utilizes...
The aim of this paper is the design and implementation of a solution for monitoring of the properties of an object, specifically a human hand in the video. Solutions available today require for their operation some special hardware, such as a depth sensor. The system described in this paper aims to acquire the properties of the object only with the aid of commercially available camera equipment. The...
In this paper, the solution for interconnecting the videoconference systems into a single videoconference infrastructure is presented. Further its users will be able to make reservations through developed web application. The paper presents complex analysis of technologies related to videoconferencing. Several ways of implementation of the web application while connecting to a central system for videoconference...
In this paper the development of simulation exercises used in blended learning are presented and further two methodologies are introduced, discussed and comparative analysis is to be carried out, pointing out the main differences. First methodology was applied on the sample of fifty students, the latter on the same number of students. Information technology tools were utilized in both methodologies,...
This paper describes a simply use case, to do students attendance using only classroom live video stream and a simply organized list of optical markers. Each student is wearing his own marker on visible part of his body. This marker exactly defines its own ID and cannot be interchanged with another one. As marker detection method / system we used Aruco markers. This selection is a result of the attached...
In this paper we propose a visual system for monitoring of student attendance in seminars and lectures. Basic idea is to estimate the number of people in the room using face detection algorithms and subsequently utilize face recognition algorithms to determine the actual identification of persons (students). Presented approach may be used for multiple purposes. Principal and primary purpose is to...
In this paper are presented the approaches and measures taken in order to enhance the learning process of computer networks. During research described in this paper we take into the consideration primarily traditional form of education, i.e. active presence of student at the institution. Enhancement itself lies in the elimination of system testing and its replacement with testing on the real devices...
This paper presents a new approach to use of the animations as a tool for education. Our approach is focused on the methodology of designing the animation rather than on the study whether it is or is not beneficial in the educational process. We will introduce the animation as a tool, present commonly used tools for development and then introduce a basic technique for developing an animation. Education...
This paper describes creation an autonomous failure-resistant multi-agent file storage, resistant against failure of hardware on certain number of its servers. We analyze multi-agent systems and ways the files are downloaded in computer networks. An agent system is analyzed, designed and implemented. The purpose of this system is to run on outdated servers and/or personal computers. Access to files...
This paper represent an approach of applying the graphical visualization methods to the educational process. The Virtual electrotechnologic factory is created based on theory and contains the theory itself. The technology utilized during the process of the development was the Flash multimedia platform. This allowed us to visualize all the theoretical processes, logically connect them and link them...
