The Scalable Video Coding Extension of the H.264/AVC Standard

We present a multimodal data set for the analysis of human affective states. The electroencephalogram (EEG) and peripheral physiological signals of 32 participants were recorded as each watched 40 one-minute long excerpts of music videos. Participants rated each video in terms of the levels of arousal, valence, like/dislike, dominance, and familiarity. For 22 of the 32 participants, frontal face video was also recorded. A novel method for stimuli selection is proposed using retrieval by affective tags from the last.fm website, video highlight detection, and an online assessment tool. An extensive analysis of the participants' ratings during the experiment is presented. Correlates between the EEG signal frequencies and the participants' ratings are investigated. Methods and results are presented for single-trial classification of arousal, valence, and like/dislike ratings using the modalities of EEG, peripheral physiological signals, and multimedia content analysis. Finally, decision fusion of the classification results from different modalities is performed. The data set is made publicly available and we encourage other researchers to use it for testing their own affective state estimation methods.

From the Publisher:
The MPEG standards are an evolving set of standards for video and audio compression. MPEG 7 technology covers the most recent developments in multimedia search and retreival, designed to standardise the description of multimedia content supporting a wide range of applications including DVD, CD and HDTV.
Multimedia content description, search and retrieval is a rapidly expanding research area due to the increasing amount of audiovisual (AV) data available. The wealth of practical applications available and currently under development (for example, large scale multimedia search engines and AV broadcast servers) has lead to the development of processing tools to create the description of AV material or to support the identification or retrieval of AV documents. Written by experts in the field, this book has been designed as a unique tutorial in the new MPEG 7 standard covering content creation, content distribution and content consumption. At present there are no books documenting the available technologies in such a comprehensive way.

Introduction to MPEG-7: Multimedia Content Description Interface

MPEG-7, formally known as the Multimedia Content Description Interface, includes standardized tools (descriptors, description schemes, and language) enabling structural, detailed descriptions of audio-visual information at different granularity levels (region, image, video segment, collection) and in different areas (content description, management, organization, navigation, and user interaction). It aims to support and facilitate a wide range of applications, such as media portals, content broadcasting, and ubiquitous multimedia. We present a high-level overview of the MPEG-7 standard. We first discuss the scope, basic terminology, and potential applications. Next, we discuss the constituent components. Then, we compare the relationship with other standards to highlight its capabilities.

Overview of the MPEG-7 standard

The MPEG-4 standardization phase has the mandate to develop algorithms for audio-visual coding allowing for interactivity, high compression, and/or universal accessibility and portability of audio and video content. In addition to the conventional "frame"-based functionalities of the MPEG-1 and MPEG-2 standards, the MPEG-4 video coding algorithm will also support access and manipulation of "objects" within video scenes. The January 1996 MPEG Video Group meeting witnessed the definition of the first version of the MPEG-4 video verification model-a milestone in the development of the MPEG-4 standard. The primary intent of the video verification model is to provide a fully defined core video coding algorithm platform for the development of the standard. As such, the structure of the MPEG-4 video verification model already gives some indication about the tools and algorithms that will be provided by the final MPEG-4 standard. The paper describes the scope of the MPEG-4 video standard and outlines the structure of the MPEG-4 video verification model under development.

The MPEG-7 visual standard under development specifies content-based descriptors that allow users or agents (or search engines) to measure similarity in images or video based on visual criteria, and can be used to efficiently identify, filter, or browse images or video based on visual content. More specifically, MPEG-7 specifies color, texture, object shape, global motion, or object motion features for this purpose. This paper outlines the aim, methodologies, and broad details of the MPEG-7 standard development for visual content description.

The MPEG-7 visual standard for content description-an overview

Tracking-by-detection is a common approach to multi-object tracking. With ever increasing performances of object detectors, the basis for a tracker becomes much more reliable. In combination with commonly higher frame rates, this poses a shift in the challenges for a successful tracker. That shift enables the deployment of much simpler tracking algorithms which can compete with more sophisticated approaches at a fraction of the computational cost. We present such an algorithm and show with thorough experiments its potential using a wide range of object detectors. The proposed method can easily run at 100K fps while outperforming the state-of-the-art on the DETRAC vehicle tracking dataset.
