On behalf of the entire Organizing Committee, we wish to welcome you to the seventeen ACM International Conference on Multimedia (ACM Multimedia 2009), held October 19-22, 2009 at the Beijing Hotel in Beijing, China.

ACM Multimedia is the premier annual ...

This paper summarizes our contribution to the Yahoo! task of the ACM Multimedia Grand Challenge. This challenge asks for the robust automatic segmentation of videos according to "narrative themes". Based on the automatic segmentation methods presented ...

Earth tremors are a constant, intrinsic part of our planet's nature and a visceral experience when first encountered.

Kosmoscope, a telematic art installation by Tim Redfern, marries two venerable technologies, the kaleidoscope and the seismograph, in ...

We describe a demonstration of four novel interaction techniques for a cubic head-coupled 3D display. The interactions illustrated include: viewing a static scene, navigating through a large landscape, playing with colliding objects inside a box, and ...

We introduce jReality, a Java library for creating real-time interactive audiovisual applications with three-dimensional computer graphics and spatialized audio. Applications written for jReality will run unchanged on software and hardware platforms ...

Today's Internet has evolved from an early experimental small-scale network to a world-wide network which infrastructure that is used on a day to day basis by companies, public bodies, governments, individuals etc. Many shortcomings of the Internet have ...

Personal authentication has attracted great attention due to its large potential of security application, and many researches have shown that fusion of features or decisions obtained from various single-modal biometrics verification systems can enhance ...

This paper presents three encoding strategies based on digital logic for steganography on Voice over IP (VoIP), which aim to enhance the embedding transparency. Differing from previous approaches, our strategies reduce the embedding distortion by ...

In speech based emotion recognition, both acoustic features extraction and features classification are usually time consuming,which obstruct the system to be real time. In this paper, we proposea novel feature selection (FSalgorithm to filter out the ...

Real tones, which are often excerpts from pop songs, have become popular as ring tones. This paper describes how a ring tone can be produced by analyzing the structure of music and selecting the most appropriate portion of the music. With audio feature ...

This paper presents a new music manipulation method that can change the timbre and phrases of an existing instrumental performance in a polyphonic sound mixture. This method consists of three primitive functions: 1) extracting and analyzing of a single ...

The following paper presents a novel audio-visual approach for unsupervised speaker locationing. Using recordings from a single, low-resolution room overview camera and a single far-field microphone, a state-of-the art audio-only speaker localization ...

Speaker clustering is the task of grouping a set of speech utterances into speaker-specific classes. The basic techniques for solving this task are similar to those used for speaker verification and identification. The hypothesis of this paper is that ...

In this paper, we present a novel stream data mining for audio steganalysis, based on second order derivative of audio streams. We extract Mel-cepstrum coefficients and Markov transition features on the second order derivative, a support vector machine ...
