An interactive authoring system for video object segmentation and annotation
نویسندگان
چکیده
An interactive authoring system is proposed for semi-automatic video object (VO) segmentation and annotation. This system features a new contour interpolation algorithm, which enables the user to define the contour of a VO on multiple frames while the computer interpolates the missing contours of this object on every frame automatically. Typical active contour (snake) model is adapted and the contour interpolation problem is decomposed into a twodirectional contour tracking problem and a merging problem. In addition, new user interaction models are designed for the user to interact with the computer. Experiments indicate that this system offers a good balance between algorithm complexity and user interaction efficiency. r 2002 Elsevier Science B.V. All rights reserved.

متن کاملInteractive Video Object Annotation
We present interactive techniques for visually annotating independently moving objects in a video stream. Features in the video are automatically tracked and grouped in an off-line preprocess that enables later interactive manipulation and annotation. Examples of such annotations include speech and thought balloons, video graffiti, hyperlinks, and path arrows. Our system also employs a directma...

This study explores the effect of online annotations via Interactive White Boards (IWBs) on reading comprehension of Iranian EFL learners. To this aim, 60 students from a language institute were selected as homogeneous based on their performance on Oxford Placement Test (2014).Then, they were randomly assigned to 3 experimental groups of 20, and subsequently exposed to the research treatment af...

Mobile TV is becoming increasingly popular. As hand held devices are personal and used in a “lean-forward” mode, mobile devices are well suited for interactive TV. The porTiVity system provides authoring tools for mobile interactive content that allow to attach interactivity to moving objects in the video. We describe automatic and semi-automatic annotation tools that create content description...
