Augmented reality for immersive remote collaboration

Dan Gelb, Anbumani Subramanian, Kar-Han Tan
2011 2011 IEEE Workshop on Person-Oriented Vision  
Abstract Video conferencing systems are designed to deliver a collaboration experience that is as close as possible to actually meeting in person.  ...  Current systems, however, do a poor job of integrating video streams presenting the users with shared collaboration content.  ...  As shown in Figure 3 , a white rectangular frame is being held up and a video clip is inserted within the frame.  ...

Background recovery from video sequences using motion parameters

Srenivas Varadarajan, Lina J. Karam, Dinei Florencio
2009 2009 IEEE International Conference on Acoustics, Speech and Signal Processing

Bringing Videos to Social Media

Stephan Kopf, Stefan Wilk, Wolfgang Effelsberg
2012 2012 IEEE International Conference on Multimedia and Expo  
We have developed a system that maps the concept of hypervideo -allowing to annotate objects in a video -to social media.  ...  Although the importance of video sharing and of social media is increasing from day to day, a full integration of videos into social media is not achieved yet.  ...  Creating a new video object is easily done with the mouse by clicking on the interactive video area and by drawing a rectangular region.  ...

Metadata Description of Thermal Videos for Rescue Operations

Andras Hajdu, Charalambos Giamas, Nicholas Vretos, Joannis Pitas
2007 2007 International Symposium on Signals, Circuits and Systems  
In this paper we present a metadata scheme for the content description of thermal videos captured during rescue operations.  ...  It has been already tested that the proposed schema can be conceptualized in ontology services, which have other input besides video analysis.  ...  A clip is a movie which contains civilian, firefighter, fire and object activity, as shown in Figure 3 .  ...

Shared interactive video for teleconferencing

Chunyuan Liao, Qiong Liu, Don Kimber, Patrick Chiu, Jonathan Foote, Lynn Wilcox
2003 Proceedings of the eleventh ACM international conference on Multimedia - MULTIMEDIA '03  
We present a system that allows remote and local participants to control devices in a meeting environment using mouse or pen based gestures "through" video windows.  ...  This naturally extends our video supported pan/tilt/zoom (PTZ) camera control system, by allowing gestures in video windows to control not only PTZ cameras, but also other devices visible in the video  ...  To provide sufficient video views of the conference environment, multiple FlySPECs were installed at different locations in the conference room.  ...

A Combined Pre-Processing and H.264-Compression Scheme for 3D Integral Images

Roger Olsson, Marten Sjostrom, Youzhi Xu
2006 2006 International Conference on Image Processing  
We first transform a still integral image into a pseudo video sequence consisting of sub-images, which is then compressed using an H.264 video encoder.  ...  However, an increase in spatial resolution of several orders of magnitude from todays 2D video is required to provide a sufficient depth fidelity, which includes motion parallax.  ...  Full parallax II-systems on the other hand can use both circular EIs positioned in a hexagonal pattern as well as rectangular EIs positioned in a rectangular pattern [2, 8] .  ...

Stranger Screens: Exploring the Application Themes for Interactive Freeform Devices

Marcos Serrano, Andrés Lucero, Pourang Irani, Anne Roudaut
2022 CHI Conference on Human Factors in Computing Systems Extended Abstracts  
In a week-long design workshop, we invited non-specialist designers to invent freeform devices and reflect on their myriad form factors and the applications they engender.  ...  Advanced technologies are increasingly enabling the creation of freeform devices: interactive devices with non-rectangular formfactors.  ...  By extension, in this paper we consider a freeform device any device not having a rectangular shape, in contrast to current laptops or smartphones for instance.  ...

Structured video and the construction of space

Judith S. Donath, Bernice E. Rogowitz, Jan P. Allebach
1995 Human Vision, Visual Processing, and Digital Display VI  
The basic units in structured video are 2 or 3D image components, rather than the rectangular frames used in traditional video.  ...  Structured Video and Space In traditional video the frame is indivisible and the sequence -a recording of events occurring in a single place and time -is the basic editing unit.  ...  With a real image, enlarging the image will lower the resolution. image is to share the destination picture with other object images, the depicted object's location in 3D space must be defined.  ...
