Introduction: This study is implemented with the aim of a systematic collecting and reviewing of conducted researches in connection with the implementation of the Radio-frequency identification (RFID) technology. Methods: This study has examined the existent literatures in databases such as Google Scholar, ISI Web of Knowledge and Science Direct by using ...

The large volume of video content generated each day has led to the need for efficient and effective methods of video indexing and retrieval. A common first step in indexing video content is to identify visually and semantically continuous segments or shots. In this paper, we present the moving query window approach to video shot boundary detection. This uses the techniques of queryby-example (...

Web servers dominate our view of the Web today. Security provided by them has been implemented with varying degrees of success. Web servers are frequently successfully attacked, with subsequent loss of corporate loss of face or revenue. Recent legislation has increased the importance of ensuring that only approved users gain access to information, which often implies filtering content served by...

We present XyView, a practical solution for fast development of user(web forms) and machine-oriented applications (web services) over a repository of heterogeneous schema-free XML documents. XyView provides the means to view such a repository as an array that can be queried using a QBE-like interface or through simple selection/projection queries. It extends the concept of universal relations i...

Content-based image retrieval is today ubiquitous in computer vision. Most systems use the query-by-example approach, performing queries such as "show me more images that look like this one’’. Most often, the user is more specifically interested in specifying an object (or region) and in retrieving more images with similar objects (or regions), as opposed to similar images as a whole. This pape...

Query-by-example is the most popular query model in recent contentbased image retrieval (CBIR) systems. A typical query image includes relevant objects (e.g., Eiffel Tower), but also irrelevant image areas (including background). The irrelevant areas limit the effectiveness of existing CBIR systems. To overcome this limitation, the system must be able to determine similarity based on relevant r...

We have carried out a detailed evaluation of the use of texture features in a query-by-example approach to image retrieval. We used 3 radically different texture feature types motivated by i) statistical, ii) psychological and iii) signal processing points of view. The features were evaluated and tested on retrieval tasks from the Corel and TRECVID2003 image collections. For the latter we also ...

Unlike traditional database management systems, in multimedia databases that support content-based retrieval over multimedia objects, it is di cult for users to express their exact information need directly in the form of a precise query. A typical interface supported by content-based retrieval systems allows users to express their query in the form of examples of objects similar to the ones th...
