Abstract

Volumetrijski sadržaj postaje sve popularniji način prikaza jer omogućuje korisniku realniji uvid u snimanu scenu i objekte. No, količina podataka potrebna za pohranu takve vrste medijskog zapisa puno je veća od standardnog dvodimenzionalnog prikaza. Iz tog razloga potreban je brz i efikasan način kompresije volumetrijskog sadržaja. U ovom radu opisani su trenutno najpoznatiji kodeci za kompresiju takvog sadržaja: G-PCC, V-PCC i Draco. Eksperimentalno su potvrđene njihove mogućnosti kodiranja na testnim volumetrijskim videozapisima kreiranim u volumetrijskom studiju tvrtke Diversitas IT, a provedena je i objektivna usporedba kvalitete kompresije navedenih algoritama PCQM metrikom. Kako još uvijek ne postoji standardizirani format pohrane volumetrijskih videozapisa, tako ne postoje ni općeprihvaćena rješenja reprodukcije istog. U ovom radu dan je pregled postojeće programske podrške za reprodukciju volumetrijskih videozapisa te formata pohrane volumetrijskih videozapisa potrebnih za njihovu reprodukciju.

Abstract (english)

Volumetric content is becoming an increasingly popular technology because it allows the user a more realistic insight into the captured scene and objects, but the amount of data needed to store this type of media record is much larger than a standard two-dimensional display. For that reason, a fast and efficient way of compressing the volumetric content is needed. This paper describes the currently best-known compression algorithms for such content: G-PCC, V-PCC and Draco. Their coding capabilities were experimentally confirmed on test volumetric videos created in the Diversitas IT’s volumetric studio, and an objective comparison of the compression quality of the above algorithms with PCQM metrics was performed. There is still no standardized format for storing volumetric videos, so there are no generally accepted solutions for their playback. This paper provides an overview of the existing volumetric video players and the storage format required for their playback.
