Abstract:

The evolution of storage capacity, computation power and connectivity in Consumer-Electronics(CE)-, in-vehicle-, medical-IT- and on-chip-networks allow the easy implementation of grid-computing-based real-time and distributed face-related analysis systems. A combination of facial-related analysis components - Service Units (SUs) – such as face detection, pose estimation, face tracking and facial feature localization provide a necessary set of basic visual descriptors required for advanced facial- and human-related feature analysis SUs, such as face recognition and facial-based mood interpretation. Smart reuse of the available computational resources across individual CE devices or across in-vehicle- or medical-IT- networks in combination with descriptor databases facilitate the establishment of a powerful analytical system applicable for various domains and applications.

Abstract - Although many different types of technologies for information systems have evolved over the last decades (such as databases, video systems, the Internet and mobile telecommunication), the integration of these technologies is just in its infancy and has the potential to introduce "intelligent" systems. This paper describes the novelties of a video content analysis in a surveillance system, demonstrating the benefits for fast retrieval in huge video databases.

Scenario:  Abandoned object.

The detection of abandoned objects is more or less the detection of idle (stationary or non-moving) objects that remain stationary over a certain period of time. The period of time is adjustable. In several types of scenes, idle objects should be detected. In a parking lot e.g., an idle object can be a parked car or a left suitcase. For this scenario we are not looking at the object types "person" or "car", but at unidentified objects, called "unknown objects". An unknown object is any object that is not a person or a vehicle. In general, unknown objects cannot move.

Benois-Pineau , P. de With, J. Han Real-Time and Distributed AV Content Analysis system for Consumer Electronics Networks

Abstract: The ever-increasing complexity of generic Multimedia-Content-Analysis-based (MCA) solutions, their processing power demanding nature and the need to prototype and assess solutions in a fast and cost-saving manner motivated the development of the Cassandra Framework. The combination of state-of-the-art network and grid-computing solutions and recently standardized interfaces facilitated the set-up of this framework, forming the basis for multiple cross-domain and cross-organizational collaborations [1]. It enables distributed computing scenario simulations for e.g. Distributed Content Analysis (DCA) across Consumer Electronics (CE) In-Home networks, but also the rapid development and assessment of complex multi-MCA-algorithm-based applications and system solutions. Furthermore, the framework’s modular nature - logical MCA units are wrapped into so-called Service Units (SU) - ease the split between system-architecture- and algorithmic-related work and additionally facilitate reusability, extensibility and upgradeability of those SUs.

P. Fonseca, J. Nesvadba Face Tracking in the Compressed Domain

Abstract: A compressed domain generic object tracking algorithm offers, in combination with a face detection algorithm, a low computational cost solution to the problem of detecting and locating faces in frames of compressed (such as MPEG-1 or MPEG-2) video sequences. Objects such as faces can thus be tracked through a compressed video stream using motion information provided by existing forward and backward motion vectors. The described solution requires only low computational resources on CE devices and offers at one and the same time sufficiently good

J. Nesvadba, F. Ernst, A. Dommisse, J. Perhavc, J. Benois-Pineau Comparison of Shot Boundary Detectors’

Abstract: Video Shot Boundary Detection (SBD) is an essential element for spatio-temporal audiovisual (AV) segmentation and video processing technologies. Platform, processing and performance constraints forced the development of various dedicated SBDs. Future platforms allow the usage of advanced SBD algorithms with higher reliability. In order to enable an appropriate trade-off decision to be made between reliability and the required processing power, benchmarking of four SBD algorithms has taken place on bases of a generic, real-world multi-genre AV corpus. In terms of complexity/performance trade-off, a field-difference based SBD proved to be optimal.

A Networked Hardware/Software Framework for the Rapid Prototyping of Multimedia Analysis Systems

Abstract: This paper describes a hardware/software framework and approach for fast integration and testing of complex real-time multimedia analysis algorithms. It enables the rapid assessment of combinations of multimedia analysis algorithms, in order to determine their usefulness in future consumer storage products. The framework described here consists of a set of networked personal computers, running a variety of multimedia analysis algorithms and a multi-media database. The database stores both multimedia content and metadata – as generated by multimedia content analysis algorithms – and maintains links between the two. The multimedia (meta)database is crucial in enabling applications to offer advanced content navigation and searching capabilities to the end-user. The full hardware/software solution functions as a test-bed for new, advanced content analysis algorithms; new algorithms are easily plugged-in into any of the networked PCs, while outdated algorithms are simply removed. Once a selected consumer system configuration has passed important user-tests, a more dedicated embedded consumer product implementation is derived in a straightforward way from the framework.

Abstract: Distribution of media in the fast growing world of digital stored content and multimedia supporting devices with connectivity, calls for a new media distribution architecture. The user should be provided with the experience of having an overview of his full media collection, regardless of the time, the place, and the connectivity. The architecture presented in this paper, fulfils these needs and can cooperate furthermore with non-compliant devices.

MediaTeam Oulu and VTT Technical Research Centre of Finland participated jointly in semantic feature extraction, manual search and interactive search tasks of TRECVID 2003. We participated to the semantic feature extraction by submitting results to 15 out of the 17 defined semantic categories. Our approach utilized spatio-temporal visual features based on correlations of quantized gradient edges and color values together with several physical features from the audio signal. Most recent version of our Video Browsing and Retrieval System (VIRE) contains an interactive cluster-temporal browser of video shots exploiting three semantic levels of similarity: visual, conceptual and lexical. The informativeness of the browser was enhanced by incorporating automatic speech transcription texts into the visual views based on shot key frames. The experimental results for interactive search task were obtained by conducting a user experiment of eight people with two system configurations: browsing by (I) visual features only (visual and conceptual browsing was allowed, no browsing with ASR text) or (II) visual features and ASR text (all semantic browsing levels were available and ASR-text content was visible). The interactive results using ASR-based features were better than the results using only visual features. This indicates the importance of successful integration of both visual and textual features for video browsing. In contrast to previous version of VIRE which performed early feature fusion by training unsupervised self-organizing maps, newest version capitalises on late fusion of features queries, which was evaluated in manual search task. This paper gives an overview of the developed system and summarises the results.

We present a new semi-automatic segmentation tool, which is motivated by the Intelligent Scissors algorithm, but which uses a modified concept of user-interaction. This new interface provides better capabilities for modifying previous segmentation results. The advantage of the new approach is that it enables to gradually increase the quality of the segmentation. The segmentation tool is based on a shortest circular path search within a corridor that is drawn by the user along the object boundary. For this purpose, we present a new algorithm for computing the shortest circular paths. Our algorithm is so fast that it almost achieves the speed of a regular non-circular shortest path search, while still ensuring an optimal solution.

abstract

The background subtraction algorithm is a frequently-used object segmentation technique because of its algorithmic simplicity. However, we show that for general rotational camera-motion, it is impractical or even impossible to use a single background image. As a solution, we propose to use multi-sprite backgrounds which enables processing of arbitrary rotational camera-motion. This paper describes a complete video-object segmentation system employing multisprites. The system generates object masks and background sprites that are compatible with the MPEG-4 object-oriented video-coding tools. Good segmentation results are also obtained for sequences, which cannot be processed with ordinary background images.

Abstract

In this paper we describe an architecture for a multi-client, multi-channel video streaming server targeted at the security market. To obtain scalability in bit-rate, multiple compressed video streams are available for each video channel. For transmission to the user, one stream has to be selected for each video channel. Parameters and cost functions to derive the optimal set of streams are defined and heuristic algorithms to find the best combination of video streams are introduced

In this paper we describe an architecture for a multi-client, multi-channel video streaming server targeted at the security market. For each connected client, the best selection of available compressed video streams per channel is made, optimising the perceived quality of the video channels requested by the client. We propose techniques to scale the bit rate per video stream and introduce a scheduling scheme to select the best video streams for a given set of channels and bandwidth constraints.

Summary:

Verification of Video Content Analysis (VCA) algorithms is quite difficult. To verify the

performance of an algorithm, the results have to be compared with the results that should

have been generated, which are called the “ground truth”. The generation of this ground truth has to be done manually. This document describes the scenarios that will be used within the CANDELA project for the verification of video content analysis systems.
