Abstract

Foreliggende oppfinnelse er relatert til en fremgangsmåte for å prege et vannmerke inn i en modell av en lineær eller plan form, særlig en ikke-unifonn rasjonell B-spline (NURBS) modell. Modellen innbefatter flertallet av splines, der kombinasjonen av disse former formen. Kontrollpunkter (P) er tildelt til splines, slik at en kurs av de respektive assosierte splines kan bli modifisert og dermed bli kontrollert ved forandring av posisjonen til kontrollpunktene (P) og/eller vekter av kontrollpunktene. Videre vil noder som er plassert i en seksjon av formen som er formet av de respektive assosierte splines, bli allokert til splines. For å forandre formen (den modifiserte kurven gar gjennom punkt Cmod) når et vannmerke blir preget inn i modellen, posisjonen til i det minste ett kontrollpunkt blir modifisert, der vekten til et kontrollpunkt påvirker formen og dermed påvirker i det minste et område av formen som blir modifisert, og/eller et tilleggskontrollpunkt blir ført inn i modellen. I det minste én tilleggsnode er ført inn i modellen (ny node i u = 1. 1875 på den modifiserte kurven) for å oppnå informasjon om hvordan forandringen av formen kan bli reversert.
