This paper presents a study developed in the scope of a larger project that aims to understand how video editing and content sharing in public displays can be used at schools to promote the informal engagement of students with curricular contents that are essential to foster future learning. The study involved a video competition where students were invited to create videos around specific peda...

Chao-Chung Cheng (SID Student Member) Chung-Te Li Liang-Gee Chen Abstract — With the maturation of three-dimensional (3-D) technologies, display systems can provide higher visual quality to enrich the viewer experience. However, the depth information required for 3-D displays is not available in conventional 2-D recorded contents. Therefore, the conversion of existing 2-D video to 3-D video bec...

The approximation functions of the directivity of the light emitting diodes (LED) have been investigated. LEDs used in large scale LED video displays have been studied. LED directional properties among the other parameters define the video display image quality. The simplicity of an approximation function and ease of analytical handling have been targeted. These functions suppose to be used in ...

High-dynamic range (HDR) imaging is expected, together with ultrahigh definition and high-frame rate video, to become a technology that may change photo, TV, and film industries. Many cameras and displays capable of capturing and rendering both HDR images and video are already available in the market. The popularity and full-public adoption of HDR content is, however, hindered by the lack of st...

Rapport technique de l'INRS-T el ecommunications no. 97-01 Preliminary work on crosstalk cancellation was carried out by Bertrand Lacotte of ENST, Paris during his stay at INRS-T el ecommunications between August and December 1995 and then described in a preliminary report 3]. The work was continued in 1996 by the other two authors. This report is an exact replica of a paper submitted to the IE...

We present 3D video fragments, a dynamic point sample framework for real-time 3D video. By generalizing 2D video pixels towards 3D irregular point samples we combine the simplicity of conventional 2D video processing with the power of more complex polygonal representations for 3D video. We propose a differential update scheme exploiting the spatio-temporal coherence of the video streams of mult...

the early 1970s, integrated-circuit memories of significant size (1 Kbit and greater) became available. These chips made it practical for the first time to build a digital memory system— specifically, what came to be known as a frame buffer—containing enough bits to hold a standard video image. Minimally, a video image contained 640 pixels horizontally, 480 pixels vertically, and 8 bits in dept...

This paper introduces the Everywhere Displays proj ector, a device that uses a rotating mirror to steer the light from an LCD/DLP projector onto different surfaces of an environment. Issues of bri ghtness, oblique projection distortion, focus, obstruction, and display resolut ion are examined. Solutions to some of these problems are described, together with a plan to use a video camera to allow...

This paper describes efficient object-based video coding schemes suitable for content-based multimedia streaming systems. Anew two video coding approaches are presented to study the effect of the object based motion estimation in video coding and the effect of the object based video coding on the compression quality, respectively. The first approach is based on a new motion estimation technique...
