Abstract

Bildebehandling utføres ved bruk av blokkbasert kompresjon, og det bestemmes om to blokker er naboblokker eller ikke. Videre bestemmes om disse to eventuelle naboblokker begge er delt opp i subblokker, men dersom det finnes at ikke begge naboblokkene er oppdelte utføres en avblokkingsfiltrering for et eller flere kantbildeelementer i disse naboblokker.
