We propose a novel Bayesian framework of symmetry-driven shape similarity to incorporate structural shape descriptor into conventional geometrical shape descriptor. We use rotation and reflection symmetries for structural shape description. Symmetry detection on each shape image provides a qualitative and a quantitative categorization of the types and the degrees of symmetry level. The posterio...

In this paper, we present a novel method for the automatic estimation of the structure of music tracks using a sequence representation. A set of timbre-related (MFCC and Spectral Contrast) and pitch-related (Pitch Class Profile) features are first extracted from the signal leading to three similarity matrices which are then combined. We then introduce the use of higher-order (2nd and 3rd order)...

A great deal of research has been conducted in the area of musical analysis. However, very little has been done with respect to utilising the MPEG-7 metadata standard to describe the structural content of music at a fine level of granularity. The aim of this paper is to provide an overview of the field of structural musical analysis and to present an architecture for the AMUSED system for autom...

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...
