Abstract

Den foreliggende oppfinnelse er relatert til pre-prosessering av videodata før koding og transmisjon. Spesielt fremviser den foreliggende oppfinnelse en fremgangsmåte for støyreduksjon i høy-tetthetsvideobilder. Dette blir realisert ved implementering av et ikke-komplekst filter som filtrerer rå pikseldatautgang fra et videokamera med lavpassegenskaper for både romlig og temporær støy kombinert med en tilpasning av filteret basert på høyfrekvensinnhold av bildet, noe som etterlater det meste av bildeinnholdet upåvirket av filtreringsprosessen.
