How to reduce the transmission latency is a main concern in the context of Mobile Visual Search (MVS). Transmitting extremely compacted visual descriptor in a progressive manner is the start-of-art solution. In this paper, we present a novel MVS system following the client-server architecture. To reduce the transmission latency, the inquiry image is represented by a set of hash bits, which are then...
In medical science field, a large amount of medical data needs to be shared in order to assist doctors to make a diagnosis and give treatment collaboratively. Traditional medical visualization systems lack cross-platform access and collaborative visualization mechanisms, it is difficult to achieve remote access and collaborative interaction. This paper proposes a collaborative interactive visualization...
In recent years, with growing demands towards big data application, various research on context-awareness has once again become active. This paper proposes a new type of context-aware user authentication that controls the authentication level of users, using the context of “physical trust relationship” that is built between users by visual contact. In our proposal, the authentication control is carried...
Mobile visual search is attracting much research attention recently. Existing works focus on addressing the limited capacity of wireless channel yet overlook its instability, thus is not adaptive to the change of channel capacity. In this paper, a novel image retrieval algorithm that is scalable to various channel condition is proposed. The proposed algorithm contains three contributions: (1) to achieve...
Modern fleet management systems typically monitor the status of hundreds of vehicles by relying on GPS and other simple sensors. Such systems experience significant problems in cases of GPS glitches as well as in areas without GPS coverage. Additionally, when the tracked vehicle is stationary, they cannot discriminate between traffic jams, service stations, parking lots, serious accidents and other...
Nowadays collaborative applications are valuable tools for scientists to share their studies and experiences, e.g. By interacting simultaneously with their data and outcomes giving feedback to other colleagues on how the data are processed. This paper presents a mobile application connected to a workflow-enabled framework to perform visualization and data filtering of large-scale, multidimensional...
This paper deals with obtaining the meteorological data (temperature, wind speed, wind direction, clouds coverage, sun rise, sun set) from the internet weather servers through free weather API functions in XML format. Together with stored operational data (traffic intensity, traffic speed, opacity, CO level…) from the existing tunnel are this data sent into the PLC based tunnel simulator through external...
This paper presents a system for crowdsourcing saliency interest points for robotically gathered 3D maps rendered on smartphones and tablets. An app was created that is capable of interactively rendering 3D reconstructions gathered with an Autonomous Underwater Vehicle. Through hundreds of thousands of logged user interactions with the models we attempt to data-mine salient interest points. To this...
Trace-oriented runtime monitoring is a very effective method to improve the reliability of distributed systems. However, for medium-scale distributed systems, existing traceoriented monitoring frameworks are either not powerful or efficient enough, or too complex and expensive to deploy and maintain. In this paper, we present MTracer, which is a lightweight trace-oriented monitoring system for mediumscale...
This paper presents an approach for using hierarchically structured multi-view features for mobile visual search. We utilize a graph model to describe the feature correspondences between multi-view images. To add features of images from new viewpoints, we designa level raising algorithm and the associated multi-view geometric verification, which are based on the properties of the hierarchical structure...
Timely detection of other vehicles in the vicinity is of extreme importance to help avoid accidents and potential loss of human life, traffic jams especially in Hilly areas with hair pins bends and reduced visibility condition in dense foggy areas. This paper introduces a GPS based system which actively and continuously sends vehicle location coordinates (latitude/longitude) to the eye in the sky...
This article deals with a design of a railway infrastructure model. The main focus is on the description of the railway network infrastructure and on design the algorithms for the railway network infrastructure model (reflecting a data structure non-oriented graph). Further attention is paid to localization of the rolling stock, visualisations of designed the railway network model and simulations...
In this paper, we propose a new computational model of driver car-following control with lateral control based on the Queuing Network (QN) cognitive architecture. A driver car-following model within the framework of the QN cognitive architecture is first developed based on the time headway and then integrated with a QN-based driver lateral control model previously validated. The comparison between...
Software architecture stands at the backbone of any software system. An up-to-date description of the architecture greatly contributes to its understanding, evaluation and evolution. Despite its importance, the architecture is typically described only in the preliminary development phases and later becomes subject of continuous degradation. Therefore, methods and corresponding tool support for reconstructing...
In this work, we have investigated the processes required for visual extracting and the remote control of KUKA KR-125 industrial robot manipulator. For this purpose, the robot controller communicates with the external system via anEthernet cable IEEE 802.3. The exchanged data are transmitted thanks to TCP/IP Protocol. To do this, we performed a client/server application with all relevant motions control...
We have developed distributed text-to-audiovisual-speech synthesizer (TTAVS) to support interactivity in computer-aided pronunciation training (CAPT) on a mobile platform. The TTAVS serves to generate audiovisual corrective feedback based on detected mispronunciations from the second language learner's speech. Our approach encodes key visemes in SVG format that are compressed by GZIP and transmitted...
In this paper, we introduce a set of new visual representations for complex systems. These visual representations allow for the efficient description of systems that encapsulate a variety of components that can be merged together to form ensembles. These ensemble methods can outperform individual approaches. The whole operation of such systems can be better interpreted using visual tools. Thus, we...
With development of content-based image retrieval (CBIR), mobile visual search (MVS) is a promising application. In typical MVS, similar images are retrieved from the database maintained by the server, given a query image taken by mobile devices. Different from general CBIR, the problem of transmission latency should be considered in MVS. In existing work, the progressive transmission is proposed...
The proliferation of mobile applications for smartphones has been based on the presence of a data connection between those devices and the Internet. Therefore, users of entry level mobile phones as well as users who cannot afford a data plan are excluded from the current dynamics of mobile applications consumption. A possible approach to include those users is the usage of SMS as the communication...
We can usually meet some complicated mathematics operations in scientific research and designing soft, though there are few functions in Visual Basic application.
