IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Cagliari dal mese di luglio 2015.
EnglishSlow motion replay and spatial zooming are special effects used in video rendering. Already consolidated as commercial features of analog video players, today both these effects are likely to be extended to the digital environment. Purpose of this paper is to present a technique combining fractals (IFS) and wavelets to obtain a subjectively pleasant zoom and slow motion of digital video sequences. Active scene detection and post processing techniques are used to reduce computational cost and improve visual quality respectively. This study shows that the proposed technique produces better results than the state of the art techniques based either on data replication or classical interpolation.

| Abstract: | Slow motion replay and spatial zooming are special effects used in video rendering. Already consolidated as commercial features of analog video players, today both these effects are likely to be extended to the digital environment. Purpose of this paper is to present a technique combining fractals (IFS) and wavelets to obtain a subjectively pleasant zoom and slow motion of digital video sequences. Active scene detection and post processing techniques are used to reduce computational cost and improve visual quality respectively. This study shows that the proposed technique produces better results than the state of the art techniques based either on data replication or classical interpolation. | |
