BACKGROUND In recent years, analyses of cleft palate speech based on phonetic transcriptions have become common. However, the results vary considerably among different studies. It cannot be excluded that differences in assessment methodology, including the recording medium, influence the results. AIMS To compare phonetic transcriptions from audio and audio/video recordings of cleft palate spe...

In this paper we describe the system designed by the ITU MSPR Group for content based video fingerprinting as applied to the TRECVID 2010 Content Based Copy Detection (CBCD) benchmark. This year focus of the system was on integration of audio and video fingerprinting to improve the robustness to attacks. The proposed system consists of three main modules: Audio/video fingerprint extraction, aud...

The ability to carry stream information over a range of network types in a managed way will become an essential requirement for telecommunication network operators as future services evolve to include the transmission of audio/video and bulk data streams. This paper details the architecture of a working pan-European demonstrator offering multimedia services through the integration of stream con...

The quality of an audio signal reproduction in the room is depending on many factors. Since the CD audio has become standard, the audio devices have to provide high quality reproduction. In comparison with video playback, where the lower resolution and frame rate is often satisfactory for the user, very high standards are expected in audio products area. High performance of the modern consumer ...

We explore the extension of an algorithmic composition system for live audio cutting to the realm of video, through a protocol for message passing between separate audio and video applications. The protocol enables fruitful musician to video artist collaboration with multiple new applications in live performance: The crowd at a gig can be cutup as video in synchrony with audio cutting, a musici...

In comparison to text, audio-video content is much more challenging to browse. Time-compression has been suggested as a key technology that can support browsing – time compression speeds-up the playback of audio-video content without causing the pitch to change. Simple forms of time-compression are starting to appear in commercial streaming-media products from Microsoft and Real Networks. In th...

This paper examines audio-visual speaker veri cation using a novel adaptation of fused hidden Markov models, in comparison to output fusion of individual classi ers in the audio and video modalities. A comparison of both hidden Markov model (HMM) and Gaussian mixture model (GMM) classi ers in both modalities under output fusion shows that the choice of audio classi er is more important than vid...

Security of digital products (audio, video, image, and text) on the internet is very essential these days, for these digital watermarking techniques are used. Digital watermarking is the process of embedding data into digital multimedia content. This is used to validate the reliability of the content or to recognize the identity of the digital content's owner. Sophisticated watermarking techniq...

This paper presents a new multiple-modality method for extracting semantic information from basketball video. The visual, motion, and audio information are extracted from video to first generate some low-level video segmentation and classification. Domain knowledge is further exploited for detecting interesting events in the basketball video. For video, both visual and motion prediction informa...
