Abstract

Wynalazek dotyczy sposobu i urządzenia do kodowania obrazu oraz sposobu i urządzenia do dekodowania obrazu. Sposób dekodowania obrazu obejmuje etapy: dekodowania entropowego (S1010) strumienia bitów, który jest odbierany, w celu odzyskania resztkowej wartości za pomocą odwrotnego kwantyzowania i odwrotnej konwersji wartości resztkowej; przeprowadzania wewnętrznego przewidywania w odniesieniu do jednostki przewidywania, która jest dzielona na co najmniej dwie jednostki przez zastosowanie sposobu asymetrycznego dzielenia na części, przy czym jednostka przewidywania, która jest dzielona zawiera pierwszą dzieloną jednostkę przewidywania i drugą dzieloną jednostkę przewidywania i odzyskiwania obrazu za pomocą dodawania wartości resztkowej do końcowej jednostki przewidywania, przy czym etap generowania końcowej jednostki przewidywania może zawierać etap interpolowania za pomocą wyznacznika filtra, który ma zmienną długość w kierunku pionowym lub poziomym w zależności długości pierwszej dzielonej jednostki przewidywania tak, że piksele, które należą do drugiej dzielonej jednostki przewidywania nie są zawarte w interpolacji.
