Abstract:
This thesis essentially adresses the scability of the indexong methods of vectorial databases. The applications concern the similarity-based search of video descriptors in large volumes in order to perform content-based copy detection. On one hand we want to perform an online monitoring of a video stream on a reference database, containing here 280000 hours of video, which means 17 billions of descriptors. The proposed solution is based on a new indexing and probalistic searching method based on a Zgrid, but also on a distorsion of the video descriptors and on a local density model. The goal i

As each individual has his/her own typical lip positions while uttering various speech sounds the system is speaker dependent.

This method is used for tracking, based on the detection results. We concatenate the location of detected bounding boxes with high-level visual features produced by convolutional networks and then predict the tracking bounding box for next frames. Because

Another approach is dynamic advertisement insertion, which inserts advertisements at run-time while the media is being streamed.

Quality of Experience (QoE) is the degree of delight or annoyance of the user of an application or service [1]. To ensure a proper level of QoE for end users, networks and service providers have to continuously monitor their systems in terms of technical parameters, which can then be used to estimate QoE. Especially for video streaming services, which consume a large amount of traffic, network problems such as bandwidth fluctuations quickly develop into annoying artefacts visible to the users, which may lead to abandonment of services.

Du point de vue théorique, le principal enjeu est de développer un cadre de tatouage unitaire en mesure de servir les deux applications mentionnées ci-dessus. Du point de vue méthodologique, le défi consiste à instancier ce cadre théorique pour servir les applications visées. La première contribution principale consiste à définir un cadre théorique pour le ta

The main topic of my diploma thesis is dedicated to the issue of wireless networks mostly aimed at IEEE 802.11 standard. Theoretical part of the thesis is divided into three main chapters. It deals with basic overview of standards, architecture, utilization of radio spectrum and modulating techniques in signal processing. Further, it describes basic security measures and quality of service requirements in WLAN networks. The thesis is complemented by two separate laboratory assignments focused on procedure related to the chosen problematic. The first assignment handles common steps to break cip

Abstract:
Video srauto šifravimas yra pagrindinis intelektinės nuosavybės užtikrinimo metodas šiuolaikinėse skaitmeninių teisių valdymo sistemose (DRM). Egzistuojantys šifravimo metodai užtikrina labai aukštą apsaugos lygį, bet tuo pat metu reikalauja labai didelių skaičiavimo resursų ir yra sunkiai pritaikomi ribotų skaičiavimo resursų mobiliems vartotojų įrenginiams. Šiame straipsnyje pristatomas dalinis MPEG-2 transporto srauto šifravimo metodas, kuris yra tinkamas tokiems ribotų resursų terminaliniams vartotojų įrenginiams. Siūlomo metodo eksperimentinio įvertinimo rezultatai rodo, kad šifravimo ir

Abstract:
For a long time, the function of the musical score has been to support activity in video games, largely by reinforcing the drama and excitement. Rather than leave the score in the background, this project explores the interaction possibilities of an adaptive video game score using real-time modulation of granular synthesis. This study evaluates a vertically re-orchestrated musical score with elements of the score being played back with granular synthesis. A game level was created where parts of the musical score utilized one granular synthesis stem, the parameters of which were controlled by t

Abstract:
This thesis work regards free viewpoint TV. The main idea is that users can switch between multiple streams in order to find views of their own choice. The purpose is to provide fast switching between the streams, so that users experience less delay while view switching. In this thesis work we will discuss different video stream switching methods in detail. Then we will discuss issues related to those stream switching methods, including transmission and switching. We shall also discuss different scenarios for fast stream switching in order to make services more interactive by minimizing delays

Abstract:
Critical media literacy (Kellner & Share, 2005) may better equip children to interpret videogame content and to create games that are nonviolent and socially just. Videogames are growing in popularity in classrooms. Yet educators and parents have concerns about the violent and stereotypical content they include. An earlier study based on the curriculum Beyond Blame: Challenging Violence in the Media (Webb, Martin, Afifi, & Kraus, 2009) examined the value of a media awareness curriculum. In this mixed-method study, I explored the effectiveness of a critical media literacy program that incorpora

This thesis discusses how to control the video content quality during the data transmission over the World Wide Web. MPEG(ISO) is the most well known video data compression standard in current web technology. The MPEG data belongs to variable bit rate (VBR) stream. Generally, when using streaming service, the server will usually use the network control protocol RTP & RTCP to change the data transfer rate. These RTP & RTCP often can not respond to the rapid changes of the network. As a r
