As the Web gains more popularity, Web sites become richer in media. Besides text, another most common form of media is image. A Web page can utilize images in various ways such as to illustrate stories, to summarize data and to decorate the page. This ...

With the advent of video sharing websites, the amount of videos on the internet grows rapidly. Web video categorization is an efficient methodology to organize the huge amount of data. In this paper, we propose an effective web video categorization ...

This video demonstration presents a new system for video summarization, called ``Near-Lossless Video Summarization" (NLVS) to tackle with the challenges of storage and indexing brought by the current boom of videos for existing online video services. ...

In this demo, a performance driven 3D face animation system is proposed. The proposed system consists of two key components: a robust non-rigid 3D tracking module and a MPEG4 compliant facial animation module. Firstly, the facial motion is tracked from ...

In this demo, we present a working system that we have built for metadata-based compressed-domain spatio-temporal video adaptation of H.264/AVC videos. Our approach is in contrast to most existing approaches that do adaptation in a series of cascaded ...

This demonstration presents an innovative framework for virtual content insertion in an interactive way. The virtual content is inserted into video with evolved animations according to predefined behaviors, and generates interactions with video ...

In this demo, we present DAVVI, a prototype of the next generation multimedia entertainment platform. It delivers multi-quality video content in a torrent-similar way like known systems from Move Networks, Microsoft and Apple do. However, it also ...

In this technical demonstration we show the current version of Arneb, a web-based system for manual annotation of videos, developed within the EU VidiVideo project. This tool has been developed with the aim of creating ground truth annotations, that can ...

NOTE FROM ACM: It has been determined that this article plagiarized the contents of a previously published paper. Therefore ACM has shut off access to this paper.

This article has been removed from the ACM Digital Library because it was found to ...

There is an increasing trend to include streamed video data in 3D environments. Such environments allow potentially several concurrently visible videos on a single display device, and consequently, network and processing bottlenecks. As a first step ...

We present MobileTI, a portable tele-immersive system that merges 3D video representations of users in real time to enable remote collaboration across geographical distances. With portability as a main goal, we address the challenges in the camera setup,...

In this paper, we present a metadata-based compressed-domain spatial adaptation scheme for H.264/AVC video. We have enhanced the H.264/AVC encoder with our proposed adaptation strategies in order to reduce video size by cropping individual frames in an ...

This paper introduces the architecture of our location sensitive indexing model which is used in a platform designed to deliver advertisements to users who primarily utilize images as queries instead of textual keywords. The indexing model facilitates ...

Community-based question answering systems have become very popular for providing answers to a wide variety of "how-to" questions. However most such systems present only textual answers. In many cases, users would prefer visual answers such as videos ...

There are still no established methods for the evaluation of browsing and exploratory search tools. In the (multimedia) information retrieval community evaluations following the Cranfield paradigm (as e.g. used in TRECVID) have been widely adopted. We ...

With the growing proliferation of conversational media and devices for generating multimedia content, the Internet has seen an expansion in websites catering to user-generated media. Most of the user-generated content is multimodal in nature as it has ...

Automatic visual categorization is critically dependent on labeled examples for supervised learning. As an alternative to traditional expert labeling, social-tagged multimedia is becoming a novel yet subjective and inaccurate source of learning ...

Facial expression recognition has many applications in multimedia processing and the development of 3D data acquisition techniques makes it possible to identify expressions using 3D shape information. In this paper, we propose an automatic facial ...

Conventional object recognition techniques rely heavily on manually annotated image datasets to achieve good performances. However, collecting high quality datasets is really laborious. In this paper, we propose a semi-supervised framework for learning ...
