Abstract

Sposób predykcyjnego kodowania mapy głębi, obejmuje następujące kroki: odbiera się mapę głębi; dzieli się mapę głębi na bloki; dokonuje się dekompozycji mapy głębi według drzewa czwórkowego na podbloki; dokonuje się przybliżenia każdego z podbloków jako płaszczyzny, która ma przypisane trzy punkty płaszczyzny (p0, p1, p2); przedstawia się zakodowaną mapę głębi w postaci zestawu płaszczyzn określonych parametrami. Sposób charakteryzuje się tym, że obejmuje ponadto następujące kroki: określa się kolejność kodowania podbloków; podczas kodowania kolejnych podbloków: oblicza się predyktory dla punktów płaszczyzny (p0, p1, p2) aktualnie kodowanego podbloku; oblicza się różnice ?p0, ?p1, ?p2 pomiędzy faktycznymi wartościami punktów płaszczyzny (p0, p1, p2) a wartościami odpowiadających im predyktorów przedstawia się parametry płaszczyzny dla aktualnie kodowanego podbloku w postaci różnic ?p0, ?p1, ?p2.
