We introduce in this paper a new approach that conveniently converts conversational videos into comics with manga-style layout. With our approach, the manga-style layout of a comic page is achieved in a content-driven manner, and the main components, including panels and word balloons, that constitute a visually pleasing comic page are intelligently organized . Our approach extracts key frames on...
Rectangular treemaps divide a rectangle and then its subdivisions in a two-dimensional space, and have high space utilization in visualizing large hierarchical datasets. Most current treemaps, however, do not clearly show the relations between the items of the same level. This paper presents a new layout called concentric rings ordered tree (CROT), which hardly wastes any space and also shows sibling...
Ontology, as one of the Protégé editing software, provides visualization functionality in the form of a plug-in. However, this has limitations due to it only illustrates the relation between super and sub classes. At the stage of develop Ontologies, it is helpful that able to see the class hierarchy and relationships using some kind of graphical tools to represent properties or restrictions linking...
With the rapid progression in information and network technologies, web-based educational environment like electronic learning (e-learning) websites and mobile learning (m-learning) websites are increasingly common to be used as a platform for teaching and learning activities. Prior studies in website design have confirmed the crucial role of aesthetics in attracting users, encouraging further exploration...
The development of several biomedical ontologies and databases for structuring and categorizing knowledge in life sciences, and particularly the ones which refer to the functions and interactions of biomolecules, have contributed to the rapid inflation of the semantic information universe that describes cellular complexity, at different scales. Together with the ever-growing number of high-throughput...
Disabled people like cerebral infraction, paraplegia, commonly lost limbs ability and lack the language ability. Most of them cannot deal with emergencies, and cannot communicate with the outside world, and lead a hard life with some loneliness and helpless. Using of visual evoked technology and Android operation system, a short message service (SMS) is designed and implemented on Pad Phone for those...
Foods consumed by children without parental supervision are not always healthy, which can cause to disease especially digestive diseases. Children should have knowledge about what is happening in their digestive and reaction after consuming food, so that they can avoid consuming bad food for their health. The medium used to convey it through games and activities is a mobile application app called...
This paper presents VEGAS - an online system that can illustrate the influence of one scientific paper on citation networks via the influence graph summarization and visualization. The system is built over an algorithm pipeline that maximizes the rate of influence flows in the final summarization. Both visualization and interaction designs are described with respect to a real usage scenario of the...
The performance of call graph analytics is critical to the development and management of large-scale software systems. Classical call graph visualizers either reuse a plain node-link graph metaphor that does not scale, or adopt the specific aggregation technique like the PivotGraph. In this paper, we first generalize the OLAP analysis framework from multidimensional data to multivariate graphs. Then...
Given a large-scale graph with millions of nodes and edges, how to reveal macro patterns of interest, like cliques, bi-partite cores, stars, and chains? Furthermore, how to visualize such patterns altogether getting insights from the graph to support wise decision-making? Although there are many algorithmic and visual techniques to analyze graphs, none of the existing approaches is able to present...
Many networks nowadays contain both positive and negative relationships, such as ratings and conflicts, which are often mixed in the layouts of network visualization represented by the layouts of node-link diagram and node indices of matrix representation. In this work, we present a visual analysis framework for visualizing signed networks through emphasizing different effects of signed edges on network...
Online discussion forums make up a significant bulk in the type of opinion information that represents a valuable source for many real-world applications. However, conducting comprehensive opinion analysis of threaded discussions is a challenging task because it requires not only an aggregation of opinions over the multi-level thread structures, but also effective methods for exploring the complex...
Web application intrusion detection systems (IDSs) are developed with the main objective is to detect web based intrusions as automatically as possible. As a result, these systems' user interfaces tend to be simple. This creates difficulties when further analyses based on these results are required. To make the outputs of web application IDSs more useful to security administrators, we propose an information...
Most cyber security research is focused on detecting network intrusions or anomalies through the use of automated methods, exploratory visual analytics systems, or real-time monitoring using dynamic visual representations. However, there has been minimal investigation of effective decision support systems for cyber analysts. This paper describes the user-centered design and development of a decision...
The paper contributes to the problem solving in semantic browsing and analysis of scientific articles. With reference to presented visual interface, four - the most popular methods of mapping including own approach - MDS with spherical topology, have been compared. For a comparison quantitative measures were applied which allowed to select the most appropriate mapping way with an accurate reflection...
The rapid expansion of the Internet and electronic commerce has encouraged many consumers to buy a variety of products online. However, due to the poor accessibility of online websites, visually impaired do not shop online or if they do, they often request help from sighted people. An online store prototype which has shopping features such as product catalogue, shopping cart and payment system was...
Liquid crystals are substances with high impact technological, new substances have been discovered and the properties of these materials need to be examined. When viewed under a microscope using a polarized light source, different liquid crystal phases will appear to have distinct textures and colors. The use of digital image processing and computer vision is being initialized in the analysis of these...
Through inducing the job task of loadmaster, the requirements for the function of loadmaster station on which the group selection with loadmaster station panel is based. According to the ergonomics standards of ground control station, combine the practical work situation of loadmaster to conduct overall design. By combining the manual layout method and intelligent layout method, the components are...
The whole states and transitions, which are occurred or are possible to be occurred are named as Workflow during a process at any work. The transitions between the states are occurred after related conditions are satisfied. On many companies, these workflows belonging to work processes are stored in database. The tracking of these processes are getting more difficult as the number of the states and...
It is a challenge to visualize high dimensional data such as project data to yield new and interesting types of insights. To address this, we augment the traditional PERT network diagram with additional nodes that represent resources, and with arcs from the resource nodes to the activities that use those resources. Subsequently, we apply various graph layout algorithms that can reveal the hidden patterns...
