Handy-Videos oder Videos von Überwachungskameras mit schlechter Auflösung können mit einer neu entwickelten Software verbessert werden, berichtete die Computerwoche gestern. Ein Forscherteam der Universität Tel Aviv hat ein Programm entwickelt, das sowohl bei Live-Material als auch bereits aufgenommenen Videos in schwarzweiß oder Farbe die Qualität deutlich verbessert. So könnten zum Beispiel Nachrichtenredaktion Handy-Videos optisch aufbereiten und diese in der Sendung zeigen. “Unsere Software wurde nicht entwickelt, um hochauflösende Kameras zu ersetzen, sondern um die Auflösung von Videos unabhängig von der zur Aufzeichnung eingesetzten Hardware zu optimieren”, so Professor Leonid Yaroslavsky, Forschungsleiter.
Die Methode, die in diesem Verfahren angewendet wird, nutzt Bilddaten aus aufeinander folgenden Frames. Diese Mehrinformationen wird in die Pixeldarstellung eingerechnet und somit die optische Qualität verbessert.
