Abstract
U razvoju algoritama za obradu i kodiranje videa, kao i kod prijenosa i pohrane videa koriste se objektivne i subjektivne metode za ocjenu njegove kvalitete. Objektivne metode koriste matematičke modele za procjenu kvalitete videa, dok se subjektivnim metodama procjena kvalitete dobije na temelju ocjena koje daju ljudi. Osnovni problemi koji se pojavljuju pri ocjenjivanju videa subjektivnom metodom su relevantnost podataka i odabir metode provođenja testa. U završnom radu su obrađene subjektivne metode, a obrađena je i primjena masovne podrške za provedbu subjektivne ocjene kvalitete videa. U namjenu prikupljanja podataka za analizu, u okviru ovog rada napravljeno je web sučelje koje je zasnovano na metodi masovne podrške. Web aplikacija omogućava izbor između 4 različite metode subjektivnog procjenjivanja: ACR, ACR-HR, DSIS i PC čije su primjene različite. Baza podataka koja je spojena s web sučeljem omogućuje registraciju velikog broja korisnika, te se na temelju testa za daltonizam određuje može li korisnik pristupiti ocjenjivanju videa, koji su komprimirani H.264 koderom. Kao krajnji rezultat ovog rada dobiveno je funkcionalno web sučelje koje se sastoji od korisničkog i administrativnog sučelja, te koje grupira rezultate ocjenjivanja prema jednoj od 4 različite metode i datumu kada je odrađen test.
Abstract (english)
In the development of algorithms for video processing and encoding, as well as in the transmission and storage of video, objective and subjective methods are used to assess its quality. Objective methods use mathematical models to assess video quality, while subjective methods use quality assessment based on ratings given by people. The main problems that occur when evaluating video by the subjective method are the relevance of the data and the choice of the method of conducting the test. The final paper deals with subjective methods and deals with the application of crowdsourcing for the implementation of subjective video quality assessment. In order to collect data for analysis, a web interface based on the crowdsourcing method was developed in the scope of this final thesis. The web application provides the application of 4 different methods of subjective video quality assessment: ACR, ACR-HR, DSIS and PC whose applications are different. The database connected to the website enables the registration of many users, and based on the color blindness test, it is determined whether the user can access the evaluation of videos, which are compressed with the H.264 encoder. As a result of this work, a functional web interface was obtained, which consists of a user and administrative interface, and sorting of the evaluation results according to one of 4 different methods and the date when the test was performed.
