Small Set

Digital video has become a very popular media in several contexts, with an ever expanding horizon of applications and uses. Thus, the amount of available video information is growing almost limitless. For this reason, video summarization continues to attract the attention of a wide spectrum of research efforts. In this work, the authors present a novel video summarization technique based on tracking local features among consecutive frames. The authors' approach operates on the uncompressed domain, and requires only a small set of consecutive frames to perform. Additionally, the authors' algorithm processes the video stream directly and produces results on the fly. The authors tested their implementation with standard available datasets, and compared the results with the most recently published work in the field. The achieved results are similar or better in quality than the best performing proposals, with the additional advantage of being able to process the stream directly in the uncompressed domain.

Internet Delivery

With Internet delivery of video content surging to an unprecedented level, online video advertising is becoming increasingly pervasive. In this chapter, we present a new advertising paradigm for online video, called contextual in-stream video advertising, which automatically associates the most relevant video ads with online videos and seamlessly inserts the ads at the most appropriate spatiotemporal positions within each individual video. Different from most current video-oriented sites that only display the ads at the predefined locations in a video, this advertising paradigm aims to embed more contextually relevant ads at less intrusive positions within the video stream nonlinearly. We introduce the following key techniques in this paradigm: video processing for ad location detection, text analysis for ad selection, and optimization for ad insertion. We also describe two recently developed systems as showcases, i.e., VideoSense and AdOn which support in-stream inline and overlay advertising, respectively.

Rare event detections are performed using spatial domain and frequency domain-based procedures. Omnipresent surveillance camera footages are increasing exponentially due course the time. Monitoring all the events manually is an insignificant and more time-consuming process. Therefore, an automated rare event detection contrivance is required to make this process manageable. In this work, a Context-Free Grammar (CFG) is developed for detecting rare events from a video stream and Artificial Neural Network (ANN) is used to train CFG. A set of dedicated algorithms are used to perform frame split process, edge detection, background subtraction and convert the processed data into CFG. The developed CFG is converted into nodes and edges to form a graph. The graph is given to the input layer of an ANN to classify normal and rare event classes. Graph derived from CFG using input video stream is used to train ANN Further the performance of developed Artificial Neural Network Based Context-Free Grammar – Rare Event Detection (ACFG-RED) is compared with other existing techniques and performance metrics such as accuracy, precision, sensitivity, recall, average processing time and average processing power are used for performance estimation and analyzed. Better performance metrics values have been observed for the ANN-CFG model compared with other techniques. The developed model will provide a better solution in detecting rare events using video streams.

In this article, I discuss how to consider the setting in online video psychotherapy. I discuss some basic principles, as well as some experiences of how to think and deal with specific problems. All of these discussions are based on the ethics of psychotherapy and the understandings of the essence of psychotherapy from the perspective of psychoanalysis.

The Way

The Colourful Heritage Project (CHP) is the first community heritage focused charitable initiative in Scotland aiming to preserve and to celebrate the contributions of early South Asian and Muslim migrants to Scotland. It has successfully collated a considerable number of oral stories to create an online video archive, providing first-hand accounts of the personal journeys and emotions of the arrival of the earliest generation of these migrants in Scotland and highlighting the inspiring lessons that can be learnt from them. The CHP’s aims are first to capture these stories, second to celebrate the community’s achievements, and third to inspire present and future South Asian, Muslim and Scottish generations. It is a community-led charitable project that has been actively documenting a collection of inspirational stories and personal accounts, uniquely told by the protagonists themselves, describing at first hand their stories and adventures. These range all the way from the time of partition itself to resettling in Pakistan, and then to their final accounts of arriving in Scotland. The video footage enables the public to see their facial expressions, feel their emotions and hear their voices, creating poignant memories of these great men and women, and helping to gain a better understanding of the South Asian and Muslim community’s earliest days in Scotland.

Mehr als zwei Drittel aller Onliner nutzen Bewegtbilder im Internet. Aufgrund hoher Reichweiten und innovativer Platzierungsmöglichkeiten entwickeln sich Werbemöglichkeiten im Bereich von Online-Video-Werbung zu interessanten Umfeldern für die Markenkommunikation. Insbesondere in den Content integrierte Werbeformate finden in diesem Zusammenhang eine besondere Beachtung, da sie das Problem der „Ad Avoidance“ umgehen und somit positiv zur Realisierung der Kommunikationsziele von Werbungtreibenden beitragen können. Diese Effekte wurden jedoch bisher noch nicht ausreichend überprüft. Der vorliegende Beitrag zeigt mittels einer experimentellen Studie, dass integrierte Online-Video-Werbung im Vergleich zu traditioneller Online-Werbung hinsichtlich zentraler Wirkungsdimensionen vorteilhaftere Werte erzielt.
