Although mobile application ecosystems have experienced tremendous growth in recent years, retrieving content of mobile applications that serves a key to mobile content search engines still faces grand challenges. Compared to web content retrieval, it ...

The paper proposes an architecture for content retrieval with smart phones, by exploiting fingerprint identification, in order to help visually impaired people to use educational material in electronic format. Use cases and design specifications are ...

Mobile cloud computing (MCC) has recently been drawing increased attention in academia as well as industry. Content retrieval is a critical service, for many mobile cloud applications and in turns relies on other resources and tools, e.g., internal ...

When no explicit annotation exists, web-based image search engines cannot understand the actual content of images. As a result they return several noisy data in most searches, leading to low precision and recall. Furthermore, usually a large number of ...

Recently, online social networks have emerged that allow people to share their multimedia files, retrieve interesting content, and discover like-minded people. These systems often provide the possibility to annotate the content with tags and ratings.

This paper presents the results of a user study carried out to evaluate an application prototype in which an audio-visual chat conversation between two users is augmented by pictures related to the topics of that conversation. The prototype analyses the ...

In recent years, the diversification and ubiquitousness of information is rapidly advancing due to the development of the information and communication technology. As for the usage of the information, the attention of sharing of information using P2P ...

Multimedia content is a dominant fraction of Internet usage today. At the same time, there is significant heterogeneity in video presentation modes and operating conditions of Internet-enabled devices that access such content. Users are often interested ...

A hierarchical organising model based-on MPEG-7 is introduced to effectively represent high-level and low-level information in soccer video. To effectively retrieve highlight clip of soccer video, adaptive abstraction is designed based on the excitement ...

Sharing of content on the internet has become more and more prevalent over the years. As the number of internet users grows exponentially, issues of scale related to content distribution and discovery have become more important. Peer to Peer networks ...

With network pipes growing fatter, peer to peer systems are fast emerging as a viable alternative to the client-server model. One of the major problems in P2P networks is the efficient and fast content distribution and search. In this paper we ...

In our living environments today, computer networks, computing devices, sensors and many other entities produce a large amount of data to be processed. This data comprise, for example, digital media content, news, computational resources like services, ...

Collaborative tagging used in online social content systems is naturally characterized by many synonyms, causing low precision retrieval. We propose a mechanism based on user preference profiles to identify synonyms that can be used to retrieve more ...

In the face of growing data archiving needs, a better approach than tape based storage is needed. We describe how a MAID based storage and data system can be designed specifically to ideally meet the many requirements of archival data. These include the ...

We present in this paper a CBIR system for use in a psychological study of the relationship between human movement and Dyslexia. The system allows access to up to 500 hours of video and is an example of a scientific user context. This user context ...

This paper proposes an automatic annotation method of sports video for content-based retrieval. Conventional methods using position information of objects such as locus, relative positions, their transitions, etc. as indices, have drawbacks that ...

A comparison of different wavelet transform based texture features for content based search and retrieval is made. These include the conventional orthogonal and bi-orthogonal wavelet transforms, tree-structured decompositions, and the Gabor wavelet ...
