| Abstract: | Článek popisuje vylepšený algoritmus pro kompresi dynamických sítí, založený na kombinaci známých technik, jako analýza hlavních komponent a EdgeBreaker. Tato kombinace umožňuje lepší kompresí vysoce detailních dynamických sítí s vyuitím prostorové a časové koherence. Součástí článku jsou experimentální výsledky srovnávající náš přístup s přístupy popsanými v literatuře. Výsledky ukazují, že použitím navrženého algoritmu je možno dosáhnout příznivějšího poměru mezi datovým tokem a degradací dat. |
| Abstract in different language: | Compression of 3D mesh animations is a topic that has received increased attention in recent years, due to increasing capabilities of modern processing and displaying hardware. In this paper we present an improved approach based on known techniques, such as principal component analysis (PCA) and EdgeBreaker, which allows efficient encoding of highly detailed dynamic meshes, exploiting both spatial and temporal coherence. We present the results of our method compared with similar approaches described in literature, showing that using our approach we can achieve better performance in terms of rate/distortion ratio. |
