In this paper a review of the most used MPEG-7 descriptors are presented. Some considerations for choosing the most proper descriptor for a particular image or video data set are outlined.

We have developed an S(N)Ar reaction-triggered fluorescence probe using a new fluorogenic compound derivatized from 7-aminocoumarin for oligonucleotides detection.

MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a contentbased description according to the recently approved MPEG7 standard. This gives to the camera a large variety of current and potential applications, such as surveillance, augmented reality, and virtual display. This paper provides an overview of what is meant by an MPEG-7 camera, ...

The ever-growing amount of audiovisual content available has raised the need to develop systems allowing each of us to consume the information considered ‘essential’, adapted to our tastes, our preferences, our time and also to our capacities of receiving, consuming and storing that information. In other words, there is an increasing need to develop systems able to automatically summarize audio...

Palladium-catalyzed ring-opening reactions of cyclopropanated 7-oxabenzonorbornadiene derivatives using alcohol nucleophiles were investigated. The optimal conditions were found to be 10 mol % PdCl2(CH3CN)2 in methanol, offering yields up to 92%. The reaction was successful using primary, secondary and tertiary alcohol nucleophiles and was compatible with a variety of substituents on cyclopropa...

This paper presents a new three-dimensional shape descriptor: 3D angular radial transform. It is an extension of the 2D region based shape descriptor proposed by MPEG7, the Angular Radial Transform (ART). We propose to generalize the ART to index 3D models.
