In this correspondence paper, we develop a teleoperated robotic 3-D mapping (TeRoM) system which enables efficient human-guided mapping of remote environments for realistic rendering and visualization. First, the hardware design of the TeRoM system is proposed which is based on a Pioneer mobile robot platform and a rotating RGB-D camera. A client/server architecture is developed to allow the data...
The multi-view video streaming is one of promising technologies for emerging video services. For those applications of multi-view video streaming, video frames of all viewpoints, i.e., cameras, are needed to be transmitted to viewers because the demands of all the viewers' view-switching are unpredictable. However, existing transmission schemes are highly vulnerable to frame loss. Specifically, the...
Disaster Prevention and Mitigation (DPM) is aimed to help people to prevent and reduce property damage in time. In this paper, we propose a DPM system called Gaia, which collects sensed data, and sends them to a back-end DPM Server with improved performance. Gaia is equipped with double 3G interfaces and Load Balancing mechanisms with Round Robin scheduling to ensure stable transmission. Furthermore...
In this position paper, we argue about a concept for collaborative outdoor reconstruction using SLAM clients and a scalable SfM engine running in the cloud. Based on previous observations and results, we discuss issues like illumination changes, overall scalability or the dacay of buildings, having a serious impact on the practical feasibility of such a system. Revisiting ideas and insights from work...
Background: According to several recent research results [1]-[4], obesity can increase the risk of many diseases such as diabetes, chronic kidney disease, metabolic disease, cardiovascular disease, etc. To prevent and treat the obesity efficiently and effectively, diet monitoring is an important factor. Purpose: Manual self-monitoring techniques for diet suffer from drawbacks such as low adherence,...
We present a method for recognizing a video that is playing on a TV screen by sampling the ambient light sensor of a user's smartphone. This improves situation awareness in pervasive systems because the phone can determine what the user is currently watching on TV. Our method works even if the phone has no direct line of sight to the TV screen, since ambient light reflected from walls is sufficient...
The working of the GPS requires a clear line of sight for accurate services. However this is a drawback when the vehicle is stuck in a long tunnel or a place where the GPS data is unavailable. In this paper we propose the TLST: Time of Arrival Based Localization and Smart Tunnels in VANETs. The paper focuses on the time of arrival and time difference of arrival based localization in the vehicular...
Today, there is a need for faster network systems wherein the information exchange can take place in fraction of seconds. In applications involving image, audio, video, server overloading problems may arise if client-server model is used. And hence, to avoid this problem XMPP can be used. The Extensible Messaging and Presence Protocol (XMPP) is an Open technology for Realtime communication. XMPP uses...
This demonstrator serves as a proof-of-concept of our multi-camera remote surveillance system that supports 1080p still image capture with a 10-second refresh rate. Image capture, compression, and broadcast are implemented in each Raspberry Pi 2 camera node. Image compression is conducted with an open-source Kvazaar HEVC encoder that outputs HEVC images in BPG format. The BPG images are broadcast...
Nowadays, IP-based physical security products like IP network camera (IPNC) are becoming essential in construction of a modern security system. In order to guarantee interoperability among them, ONVIF has been a de facto standard communication framework. In addition to core specification, ONVIF defines many services. ONVIF Event service is supposed to provide notification messages to registered clients...
The scarcity and misuse of fresh water pose a serious and growing threat to sustainable development. The population growth, severe droughts and uneven distribution of water resources are the reasons for water scarcity, and this scarcity will only continue to grow more severe. The technical sophistication of meters for measuring water flows has increased noticeably in recent decades in order to improve...
Streaming Feed has become one of the most used utility now-a-days. Starting from Home-Security to Business Surveillance, streaming feed is utilized everywhere. However, due to unstable network bandwidth, frequent buffering and delay occurrence usually creates degraded user experience. One of the ways to avoid this is to use Adaptive Bit rate Streaming. Among various protocols supporting this Adaptive...
Single-Camera Video Surveillance (SCVS) has mainly been applied in the passive monitoring. Video surveillance covers small area, the video information is not sufficient without the joint tracking capability. Currently poor performance in most similar networks is mainly due to unintelligence and low real-time. In this paper we proposed a distributed smart multi-eyes camera network by utilizing smart...
We present Robot Devastation, a multiplayer augmented reality game using low-cost robots. Players can assemble their low-cost robotic platforms and connect them to the central server, commanding them through their home PCs. Several low-cost platforms were developed and tested inside the game.
DARPA Robotics Challenge left not only technology development in the humanoid field but also increase of the attention on humanoids and the motivation to become a humanoid developer to people. However, the reality is not so simple. To develop a humanoid which has enough DOF and performance, it costs too much and most people in the world cannot own one. In this research, we propose the LoE (League...
Digital technologies enable indoor location management for determining and tracking the position of a person through various sensing mechanisms. This emerging area has a wide range of applications in the service industry to improve business processes. Location management is aided by the proliferation of mobile devices which open many exciting possibilities with their rich sensor set. We present a...
In this paper we conduct an intensive investigation into a recent remote collaboration support system called t-Room. This system virtually overlays a room onto other distant rooms using media data processing technologies, and it provides users in the distant rooms the sense of being in the same room. We improve t-Room by expanding its shared room space. We first introduce our own t-Room system, which...
Many homes are still not considered environmentally friendly. In addition, home safety and comfort is still an issue today. Because of that, energy efficient, safe and comfortable home that can act intelligently in order to solve the problems and meet the needs of its users need to be created. That is to create a single unified management system in a home. In this thesis, intelligent home management...
c-Space aims to stimulate users' creativity by giving them a set of tools that would allow the reconstruction of 3D scenes by just taking some pictures/videos of the real world. Of great importance is the possibility to exploit these tools in a mobile environment, in order to utilize the portability and accessibility offered by hand-held devices. However, the decision to support this kind of devices...
Video surveillance service has become one of the most popular services of video data center. Different from traditional VoD and IPTV services, video surveillance service is based on video data center which receives video stream from IP camera and forward the video stream to end user. However, current works only consider the forwarding video stream scheduling from media server to end user and focus...
