We present a general approach to temporal media segmentation using supervised classification. Given standard low-level features representing each time sample, we build intermediate features via pairwi...
We consider the problem of large scale retrieval evaluation. Recently two methods based on random sampling were proposed as a solution to the extensive effort required to judge tens of thousands of do...
We consider the problem of evaluating retrieval systems with incomplete relevance judgments. Recently, Buckley and Voorhees showed that standard measures of retrieval performance are not robust to inc...
Video retrieval – searching and retrieving videos relevant to a given query – is one of the most popular topics in both real life applications and multimedia research. Finding relevant video content i...
Traditional program guides, TV applications, and online portals alone are no longer sufficient to expose all content, let alone offer the content that consumers want, at the times they are most likely...
This tutorial lays the foundation for the exciting new horizons that arise when multimedia data can automatically be indexed by its semantic content. It will cover basic video analysis techniques, exp...
This study reports about the detection of non-natural structures in outdoor natural scenes. In particular, we present a new approach based on ridgelet transform for the segmentation of man- made objec...
This paper reports on the activities of the INEX 2005 Multimedia track. The track was successful in realizing its objective to provide a pilot evaluation platform for the evaluation of retrieval strat...
This paper presents the semantic pathfinder architecture for generic indexing of multimedia archives. The semantic pathfinder extracts semantic concepts from video by exploring different paths through...
This paper describes the automatic assignment of images into classes described by individual keywords provided with the Corel data set. Automatic image annotation technology aims to provide an efficie...
This contribution addresses generation of natural language descriptions for human actions, behaviour and their relations with other objects observed in video streams. The work starts with implementati...
The results of a study are presented, in which people queried a news archive using an interactive video retrieval system. 242 search sessions by 39 participants on 24 topics were assessed. Before, dur...
The number, and size, of digital video databases is continuously growing. Unfortunately, most, if not all, of the video content in these databases is stored without any sort of indexing or analysis an...
The authors developed a system in which visually dense displays of thumbnail imagery in storyboard views are used for shot-based video retrieval. The views allow for effective retrieval, as evidenced ...
The INEX Multimedia track focuses on using the structure of XML documents to extract, relate, and combine the relevance of different multimedia fragments. This paper presents a brief overview of the t...
Technological developments in content-based analysis of digital video information are undergoing much progress, with ideas for fully automatic systems now being proposed and demonstrated. Yet because ...
Research in Information Retrieval has significantly benefited from the availability of standard test collections and the use of these collections for comparative evaluation of the effectiveness of dif...
Recent years have seen the development of different modalities for video retrieval. The most common of these are (1) to use text from speech recognition or closed captions, (2) to match keyframes usin...
Query-by-keyword is the paradigm on which machine-based text search is still based. Elaborating on the success of text-based search engines, query-by-keyword also gains momentum in multimedia retrieva...
