Dashboard cameras are increasingly used these days worldwide to record driving videos. These devices generate a vast amount of geo-referenced videos. However, most of this valuable data is lost due to loop recording. We present the City Recorder, a platform to provide street level video tours based on user-uploaded driving videos. We demonstrate here how to get a smooth route previewing experience...
There were many research works about video surveillance as a service system. Some concerned system architecture. Some identified cost optimization for the deployment of video surveillance systems using cloud computing technology. However, there was not much information about budget calculation for system provision. This paper addresses a cost investigation for video surveillance providers to use as...
Digital signage service provides advertisement and information to users using electronic displays with network capabilities. Compared to traditional DID (Digital Information Device) that just provides contents one-way, digital signage service can provide more advanced functionalities such as user interaction and audience measurements. By measuring audience behavior, it is possible to provide appropriate...
This paper presents the architecture of an extended area monitoring system based on crowdsourcing and mobile devices. In particular areas (as very large historical sites) it can be difficult or impossible to install fixed cameras due to the huge number of candidate points of interest (POI) to monitoring or to the significant impact on site (i.e. cameras or other sensors could be too invasive towards...
In this paper, we present a novel method to protect privacy information for the Cloud based Video Storage System (CVSS). We present how this system stores the video stream data transferred from the network connected camera such as IP CCTV. As the system receives the video stream, it masks the privacy related part, such as facial information or car plate number and so on, of the video stream data with...
Recently, in manufacturing, machinery, construction and shipbuilding industry, diversified researches of visualizing design drawings without difficulty utilizing augmented reality technology have been performed. In this paper, we propose efficient 3D design drawing visualization technique based on mobile augmented reality. Proposed technique first recognizes design drawing region, and only performs...
Overseas patent lawsuits and infringements of intellectual property rights have been increasing. As the Internet expands and globalization progresses, Japanese companies become more exposed to the risk of lawsuits overseas. Thus, digital forensics technology has been attracting attention. This technology enables the digital data a company manages to be disclosed as proof when a lawsuit is generated...
A smartphone application that displays a live view of road traffic can provide drivers with real-time information on traffic jams, flash floods or accidents along their planned routes. This information aids them in avoiding delays and uncertainties on the road, enhancing their navigation experience. Several US departments of transportation provide information from street cameras in the form of a snapshot...
The paper reports the hitherto obtained results of the research project that deals with scene representations that are suitable for free navigation around the scene. These scene representations are acquired from a limited number of cameras located around the scene. The project is aimed at the development of an efficient compression technology and the experimental environment for testing such technology...
Recent advances in image-based localization have made it possible to estimate the camera pose relative to 3D point clouds. In a multimedia cloud computing paradigm, large-scale 3D point clouds can be stored on the server side, and this enables us to implement image-based localization applications on mobile devices toward many cloud-media applications and services. When scaling the 3D point cloud database...
In tele-presence systems, direct face-to-face contact, is essential for emotional communication as it carries non-verbal clues. In commercial products, face-to-face contact is approximated by using either a large semi-transparent mirror to project an image of the remote participant and capture the local participant image by using a video camera aiming at the centre of the screen or by using low profile...
The paper reports the proof-of-concept tests, i.e. ergonomic, non-mobility tests with participation of blind volunteers and emphatic field trials (i.e. with the participation of sighted individuals) of a teleassistance system for the visually impaired. The system consists of two terminals connected by the GSM and Internet networks. The mobile terminal, housing a digital camera, GPS receiver and headset,...
This paper summarizes the steps that were followed in the creation of a dynamic webpage for publishing, in real time, the data from the Environmental Noise Monitoring station installed at the Association for the Development of Industrial Aerodynamics (ADAI), at the University of Coimbra. The webpage has been used as part of a remote laboratory activity in a distance learning course about indoor environment...
The proliferation of mobile cameras has popularized social sharing of videos captured at events such as sports matches, art performances, and lectures. Due to bandwidth and energy constraints, it is often not efficient or desirable to upload all captured videos to a server for sharing immediately after capturing. We propose a pull-based, on-demand mobile video sharing system that allows user to share...
Delivering high resolution, high bitrate panorama video to a large number of users introduces huge scaling challenges. To reduce the resource requirement, researchers have earlier proposed tiling in order to deliver different qualities in different spatial parts of the video. In our work, providing an interactive moving virtual camera to each user, tiling may be used to reduce the quality depending...
In the event of natural or man-made disasters, many videos may be collected by civilians and surveillance cameras that can be extremely useful for first responders trying to ascertain the extent of the damage. However, watching and analyzing numerous videos on separate screens can be a cumbersome task. Registering a set of 2D videos with a 3D model can provide an intuitive venue for viewing multiple...
In this paper, we propose a secured management solution for using BYOD safely for business applications. The proposed system is capable of providing 1) secured authentication for BYOD devices, 2) selective BYOD device functionality disabler and enabler, and 3) supports for various mobile operating systems (Android, iOS, Windows Phone). We demonstrate the functionalities of system through an implementation...
This paper presents a content-based multimedia indexing and retrieval framework designed for mobile platforms running Symbian-based operating system. It is mainly developed by focusing on mobile platform restrictions and Symbian features. The proposed framework is built on a client-server architecture, where the client side basically consists of the user interface and controllers, and the server is...
Distributed smart cameras exploit smartphone processor performance in their node communication and video metadata exchange, allowing the network to collectively reason in interpreting the scene, generating alerts, and making decisions.
The research in this paper focused on the development of a general purpose helpdesk system on a multi-touch panel for a collage or an institution. This system is implemented on Multi-touch technology under NUI (Natural User Interface). The developed helpdesk system would be able to help the guest and in-campus persons without any kind of special training, just by touching the surface or with usual...
