Replay detection is a pivotal step for sports video highlight extraction, which is a very promising application of multimedia analysis. In this paper, a general framework, which is based on a Bayesian network, is proposed to make full use of the multiple ...

The retrieval of multimedia data relies on a feature extractor to provide the intrinsic characteristics (features) from the data, and a measure to quantify the similarity between them. A challenge in multimedia database systems is how to best integrate ...

We present a general framework for cross-media annotation that can be used to support the many different forms and uses of annotation. Specifically, we discuss the need for digital annotation of printed materials and describe how various technologies ...

This paper presented a new kind of query, global nearest neighbors query, which is based on a special distance, global distance, between two objects during given time interval. According to the relationship with continuous nearest neighbor query, a native ...

The uncertainty management problem for moving objects databases has been well studied recently, with many models and algorithms proposed. However, very limited work has dealt with the index of uncertain trajectories for a running moving objects database. ...

Let a text of u characters over an alphabet of size σ be compressible to n phrases by the LZ78 algorithm. We show how to build a data structure based on the Ziv-Lempel trie, called the LZ-index, that takes 4n log2 ...

Image retrieval has found more and more applications. Due to the well recognized semantic gap problem, the accuracy and the recall of image similarity search are often still low. As an effective method to improve the quality of image retrieval, the relevance ...

We present a document routing and index partitioning scheme for scalable similarity-based search of documents in a large corpus. We consider the case when similarity-based search is performed by finding documents that have features in common with the ...

One of the key components of tele-presence systems is automatic awareness of the remote environment. This very same capability of automatic situation awareness is currently being developed and deployed in the context of the next generation smart surveillance ...

In this work, we systematically study the problem of event recognition in unconstrained news video sequences. We adopt the discriminative kernel-based method for which video clip similarity plays an important role. First, we represent a video clip as ...

Automatic information retrieval in the field of shape recognition has been widely covered by many research fields. Various techniques have been developed using different approaches such as intensity-based, model-based and shape-based methods. Whichever ...

This paper describes a fast and easy-to-use simultaneous alignment method of multiple range images. The most time consuming part of alignment process is searching corresponding points. Although "Inverse calibration" method quickly searches corresponding ...

We present an original approach for motion-based video retrieval involving partial query. More precisely, we propose a unified statistical framework allowing us to simultaneously extract entities of interest in video shots and supply the associated content-based ...

This paper focuses on the stability-based approach for estimating the number of clusters K in microarray data. The cluster stability approach amounts to performing clustering successively over random subsets of the available data and evaluating ...

The B⁺-tree and its variants have been reported as the good index structures for retrieving data. Database systems frequently establish the B⁺-tree style indices for fast access to data records. However, traditional B⁺-tree ...

Recently, video clips have become very popular online. The massive influx of video clips has created an urgent need for video search engines to facilitate retrieving relevant clips. Different from traditional long videos, a video clip is a short video ...
