Automated Camerawork for Capturing Desktop Presentations — Camerawork Design and Evaluation in Virtual and Real Scenes

چکیده
This paper introduces a novel automated camera control method for capturing desktop presentations. For this purpose, we first discuss typical features of shots and their cameraworks that frequently appear in TV programs. To realize those features in our automated video capturing system, we classify the purpose of a camerawork from two points of view: target and aspect-of-target. Then, we consider the correspondence between the classification and typical shots and cameraworks. We propose the virtual-frame control algorithm based on this idea, and the implementation in our video production system. We then show experimental results that verified our method through two kinds of experiments: virtual video capturing using CG animations and real video capturing of real presentations.

Camerawork for Comics Generated from Visitors' Experiences in a Virtual Museum
We present a camerawork module for representing events in a virtual museum with a comic style. The module uses four basic camera shots, i.e., internal, external, apex, and group, to compose a shot sequence of two main events happening in a museum, i.e., move and stay. This module is fully implemented in a comic generation system we have been developing for summarizing user experiences in Second...
متن کاملVisualization of Text-Based Dialog in a Virtual Classroom for e-Learning
We have developed a visualization system for dialog text exchanged in e-learning virtual classrooms. In this system, text-based online discussions among learners are effectively visualized as discussions held in a virtual classroom in cyberspace. Discussion participants are displayed as avatars. The virtual classroom maintains the interest of learners because it incorporates professional camera...
متن کاملCollaborative idea construction: Repetition of gestures and talk in joint brainstorming
This study examines the roles of gesture repetition in the process of collaboratively shaping ideas. The data involve three college students brainstorming for the production of a short film. Employing primarily language and depictive gestures, the participants collaboratively shape ideas of the film scenes, characters’ actions, and camerawork; they accept or reject each other’s proposals, elabo...

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...
متن کاملImproving the Camerawork of Casual Video
This article presents an approach to postprocessing casually captured videos to improve apparent camera movement. Recinematography transforms each frame of a video such that the video better follows cinematic conventions. The approach breaks a video into shorter segments. Segments of the source video where there is no intentional camera movement are made to appear as if the camera is completely...
