  <dc:title xml:lang="srp">Fraktalna i multifraktalna karakterizacija 3D video formata</dc:title>
  <dc:description xml:lang="srp">Trodimenzionalni (3D) video sadržaj postaje sve prisutniji u saobracaju
žicanih i bežicnih mreža. Kako 3D video karakteriše velika kolicina podataka,
njegovo prisustvo u mreži predstavlja znacajano opterecenje za saobracaj mreže, pa
je neophodno poboljšanje u nacinu prenosa ove vrste signala.
Predmet ovog rada je fraktalna i multifraktalna karakterizacija 3D video formata
sa ciljevima pokazivanja da 3D video ima fraktalne i multifraktalne osobine i opisivanja
ovih svojstava, poreenja svojstava za razlicite video formate i mogucih primena
u usavršavanju modelovanja saobracaja 3D video formata i razvijanju boljih tehnika
za prenos, smoothing i statisticko multipleksiranje videa.
Izvršeno je kreiranje algoritama i softverska realizacija u programima Matlab
i Python, u okviru matematicke metode iz oblasti kompleksnih sistema i haosa,
za odreivanje fraktalnih osobina (metoda agregacije varijanse (aggregated variance
method), R/S statisticki metod (R/S statistic method) i metod više skala (multiscale
method) za odreivanje Hurst-vog indeksa) i multifraktalnih osobina (metoda
momenta za multifraktalne spektre i procenu generalizovane dimenzije, metoda histograma
za multifraktalne spektre i inverznu multifraktalnu analizu). Na osnovu
dobijenih rezultata potvrene su fraktalne i multifraktalne osobine 3D video formata
i izvršeno njihovo poreenje, uzimajuci u obzir format 3D videa, strukturu, tipove
frejmova, kvantizacione parametre kodera, agregaciju frejmova i metode emitovanja...</dc:description>
  <dc:description xml:lang="eng">Three-dimensional (3D) videos are becoming increasingly
present in wireland and wireless networks, and due to the high data content they
present significant load in the network. This impact of 3D video on network traffic
causes a need of improving means to handle this type of data.
Subject of this thesis is fractal and multifractal characterization of 3D video
formats with the main goals to show that 3D video has fractal and multifractal
properties, to describe them, to compare these properties for different 3D formats, for
possible applications in traffic modeling of 3D video formats and for the development
of improved transport techniques for smoothing and statistical multiplexing of video.
Algorithms and software realizations for mathematical methods in the area of
complex systems and chaos were developed in Matlab and Python, for determination
of fractal properties (the aggregated variance method, the R/S statistic method,
and the multiscale method) and multifractal properties (the method of moments for
multifractal spectra and estimation of the generalized dimensions and the histogram
method for multifractal spectra and inverse multifractal analysis). Based on the obtained
results, fractal and multifractal properties of 3D video formats are confirmed,
their comparison is performed, for various 3D video formats, video structures, frame
types, values of the encoder quantization parameters, aggregation of the frames, and
streaming method of video...</dc:description>
