A fast and systematic algorithm for detecting and classifying edge components of each block in discrete cosine transform (DCT)-compressed images. Expand

We present nonnegative matrix partial co-factorization (NMPCF) where the target matrix (spectrograms of music) and drum-only-matrix (collected from various drums) are simultaneously decomposed, sharing some factor matrix partially, to force some portion of basis vectors to be associated with drums only.

An interactive audio service is a new conceptual audio service that provides the users with opportunities for a variety of experiences on the alternative and advanced audio services. Expand

We address a problem of separating drum sources from monaural mixtures of polyphonic music containing various pitched instruments as well as drums. Expand

In this paper, we introduce an agent-based multimedia broadcasting framework using the Foundation for Intelligent Physical Agents (FIPA) and MPEG-7 technologies within MPEG-21. Expand

An unsupervised method is proposed aiming at extracting rhythmic sources from commercial polyphonic music whose number of channels is limited to one. Expand

A reconfigured T/F structure is also proposed to enhance the generating performance of sound scenes such as ‘karaoke’ and ‘solo’ play in interactive music scenarios. Expand

The paper presents the first results of research on the MPEG-7 interface over MPEG-4 systems, which makes it easy to search MPEG- 4 content. Expand

A video summary abstracts the entirety with the gist without losing the essential content of the original video and also facilitates efficient content‐based access to the desired content. Expand
