Abstract

Apparat for å kode et digitalt video- signal (217) for overføring ved redusert hastighet, med en såkalt nøkkelpunktbasert bevegelsesendringskompensasjonskrets(150). Et sett nøkkelpunkter velges i et rekon- struert referanseenkeltbilde, representert av en sekvens i videosignalet, og et sett endringsvektorer dannes som forskjellen mellom nøkkelpunktene i et aktuelt enkelt- bilde og et opprinnelig referanseenkelt- bilde. Ved estimering (prediksjon) frem- bringes et nytt enkeltbilde ut fra settet av endringsvektorer og det rekonstruerte referanseenkeltbilde, i en konvergensprosess hvor seks triangler affintransfomieres uav- hengig ved hjelp av forskyvningene av topp- punktene. Hvis forskyvningen gir et bedre signal/støyforhold, oppdateres punktenes endringsvektorer seJcvensielt. Dermed oppnås en effektiv estimering og rekonstruksjon av enkeltbilder slik at de best mulig sammenfaller med de opprinnelige bilder, også ved zooming, rotasjon og skalering.
