Recently, investigating boundary prior to aid other low-level image cues, have gained great attention in salient object detection. Although the salient regions are mostly located in the image center, the inverse might not necessarily be true. In addition, such kind of center-bias assumption is very simple and fragile, especially when salient regions often touch the image boundary or the images are...
In this paper, we present an animation developed in the Wolfram Mathematica System for the visualization of the m-convex hull of sets containing finitely many points on the Cartesian plane.
We present a design space exploration of interaction techniques for supporting multiple collaborators exploring data on a shared large display. Our proposed solution is based on users controlling individual lenses using both explicit gestures as well as proxemics: the spatial relations between people and physical artifacts such as their distance, orientation, and movement. We discuss different design...
Social network emanates from socially interacting entities that are represented as nodes with identical properties. These nodes are interconnected through different forms of relationship among them. Social network analysis (SNA) establishes interactions and defines the relationships on basis of theoretical foundation of networks and graphs. Social media involves in exploring several ways people share...
DBLP (Digital Bibliography & Library Project) has the huge collection (around 3.4 million) of journal articles with its meta data, papers published in various national and international conferences, and other number of online publications in the field of computer science. Research data on DBLP increases enormously which arises many research problems in the domain of bibliography data network analysis...
This paper objective is to analyze LBP and CM for the comparative analysis in the field of content based image retrieval (CBIR). In this paper LBP and CM methods are used for the efficient retrieval of the images from the Wang database. All the 10 classes are used for the results comparison. LBP is used for better thresholding and CM is used with color dominant features for the efficient retrieval...
Archaeology is a broad church and its role as a “two culture” discipline is frequently cited. This position at the interface of the arts and sciences remains central to archaeological activity but there have been significant changes in the structure of archaeology and its relationship to society overall. The growth of heritage science, in particular, is driving change and development within archaeology...
Electrooculogram is record of eye movement using surface electrodes. EOG signals are analyzed in many areas using various methods. In this study, EOG signals were recorded from male and female volunteer university students before and after exam to examine capability of following visual stimulant. Volunteers followed visual test program on computer. In the meantime EOG signals were recorded simultaneously...
Though some games for visually impaired persons have been developed, most of games that use only auditory information present challenges for sighted persons. Moreover, unfortunately, it is still difficult for visually impaired persons to play the same game with sighted persons and for sighted and visually impaired persons to share a common subject. Thus, we developed a barrier-free game that both...
We collect environmental information through our sensory organs, perceive them suitably to execute the task in hand. Examples of such tasks are abundant, like driving, operating machines, playing games, hunting, or mushroom picking on mountains. While executing such tasks, there is a marked difference in efficiency and accuracy between an expert and a novice. An expert is attentive to only what is...
Over the last decade, there has been a gradual increase in the number of people with mobility and speech impairments who require novel communication devices. Most of the recent works focus on the Latin script; there is a lack of appropriate assistive devices for scripts that are specific to a country. In this paper, we propose a novel multimodal Hindi language virtual keyboard based on a menu selection...
Passive brain-computer interfacing allows computer systems direct access to aspects of their user's cognition. In essence, a computer system can gain information about its user without this user needing to explicitly communicate it. Based on this information, human-computer interaction can be made more symmetrical, solving an age-old but still fundamental problem of present-day interaction techniques...
The article presents an eye tracking analysis based study in context of learning IT skills. The goal of eye tracking analysis is to determine the gaze movement differences between students with different prior knowledge during answering a question in the topic of computer networks. The gaze movement was tracked by cost-effective Eye Tribe tracker, and the eye movement data was evaluated by Ogama software...
Digital videos play an important role today: they are used for entertainment, for communication and for information exchange. Within the internet, there are many sources that provide video content in different ways. Videos can be streamed in real-time or downloaded for local usage. In all these scenarios, video content is exchanged using some sort of binary serialization format. Consequently, compatible...
As the needs of education of programming language increase, the importance of the learning environment has been emphasized. Based on the social trends, various web services for the education of programming which improves the computational thinking of a student. Among the web services, block-based programming languages are well known as an effective educational tool for a primary student though a freshman...
It has been shown in numerous studies that the application of Augmented Reality (AR) to teaching and learning is beneficial, but determining the reasons behind its effectiveness, and in particular the characteristics of students for whom an AR is best suited, can bring forth new opportunities to integrate adaptive instruction and AR in the future. Through a quasi-experimental research design, our...
An Immersive Audio Environment (IAE) system is designed for the application of Unmanned Ground Vehicles (UGV). The IAE system consists of a small sized microphone array, ADC, beamformers for the UGVs, Head Related Transfer Function (HRTF) filters, DAC, earphones for remote operators. The proposed IAE system is built by integrating commercial-off-the-shelf (COTS) products with a sound synthesis system...
The topic presented in this paper covers statistical studies on illumination conducted using specialised software dedicated to such simulations. A pre-designed computer visualisation of illumination, which included zonal illuminations of a selected architectural structure was modified by a selected group of respondents. As a result of responders individual aesthetic preferences sets of average luminance...
La rehabilitación física de pacientes está sufriendo una modificación en su forma con la llegada de las nuevas tecnologías que permiten captar el movimiento de los pacientes. Esto supone un gran avance que facilita la repetición constante de los ejercicios con una correcta monitorización de posibles errores, la guía para que los pacientes realicen los ejercicios de forma correcta, evita costosos e...
In this paper the results of detailed analysis of asymmetric wall lighting in given interior are presented. The effects of wall lighting as a function of distance between wall and line of luminaires are examined. The aim is to find the optimum distance between the wall and the line of luminaires, according to author's criteria, giving the best wall lighting uniformity. Comparing the results, the best...
