The approach proposed by the ENTHRONE project to solve the end-to-end quality of service problem in a scalable manner is to establish, and activate when needed, long-term quality of service enabled aggregate pipes over multi-domain environments for the subsequent transport of individual flows from multimedia content providers to multimedia content consumers. Based on this approach, this paper proposes admission control schemes both at the granularity of individual flows and aggregate demands. Through simulations we show the proper joint operation of the schemes, their ability to provide quality of service, resource utilization gains and to minimize service rejection probabilities.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132398140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rushes are often single¿shot sequences at a single location, sparsely edited, with repetitive content and soundtrack is frequently irrelevant. This leads to additional challenges beyond the existing ones in multimedia indexing and retrieval. The joint effort of a number of research groups all over the world resulted in a ‘rushes exploitation’ task in the TRECVID video analysis international benchmark organized this year. In addition, the European FP6 project RUSHES is fully dedicated to research and development of a system for indexing, accessing and delivering raw, unedited audio¿visual footage and to enable indexing, search and retrieval of rushes archives to ease in¿house postproduction or reuse in a media professional environment. In this special session, latest research results on indexing, search and retrieval with focus on raw unedited audiovisual content are presented.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122872440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Segment Based Diffusion - A Post-Processing Step (Not Only) for Background Subtraction 基于片段的扩散-一个后处理步骤(不只是)背景减法

Background subtraction starts by estimating a model of the background image of a scene and then calculating the likeliness that a given pixel of the current camera image belongs to the background model. Typically this is done by subtracting the background image from a given frame, where the difference image is usually thresholded and post-processed to find object boundaries. In this paper we present a method for enhanced post-processing that exploits color and texture information of the original video frame. This way we are able to extract pixel-exact object boundaries. Based on direct color segmentation of the video frame, an iterative method analog to biological diffusion and physical heat transfer processes, spreads information from the difference image over segment boundaries. For this purpose, diffusion resistances are defined between adjacent segments, based on color and texture similarities and common contour length. An iterative process calculates and transfers the flux of 'difference energy' between segments of the difference image. The resulting image allows for easy segmentation by thresholding. Experimental results show the validity of our approach.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126399743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This feature is named FCTH - Fuzzy Color and Texture Histogram - and results from the combination of 3 fuzzy systems. FCTH size is limited to 72 bytes per image, rendering this descriptor suitable for use in large image databases. The proposed feature is appropriate for accurately retrieving images even in distortion cases such as deformations, noise and smoothing. It is tested on a large number of images selected from proprietary image databases or randomly retrieved from popular search engines. To evaluate the performance of the proposed feature, the averaged normalized modified retrieval rank was used.

SVC provides an elegant solution to adapt the video content, as it allows terminal and/or gateways accessing only a sub-part of the stream, without affecting the semantics of the source video signal. This paper describes adaptation mechanisms based on SVC, focusing on the implementation in the context of the IST project ENTHRONE. A particular emphasis is placed on adaptation techniques based on SVC NAL unit header extension, and on innovative RTP packet loss handling mechanisms, specifically conceived to handle losses in scenarios where SVC to SVC and SVC to H.264/AVC adaptation is performed and layered multicast cannot be used.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129823456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multi-objective learning mechanism is designed to derive a suitable merging metric for different features. The core of this mechanism is a widely used optimisation method - the multi-objective optimisation strategies.

We examine related efforts on the modeling of large video semantic spaces and review public evaluations such as TRECVID, which are greatly facilitating research and development on video retrieval.
